Let's explore the potential solutions you've gathered to get you back into the surreal world of Clair Obscur.

Fix Clair Obscur Expedition 33 Fatal Error

Here are the detailed steps to fix the Clair Obscur Expedition 33 fatal error:

1. Fresh Install of Windows 11

A clean installation of your operating system can often resolve deep-seated software conflicts and performance-related issues that might be contributing to game crashes. Here's a proper way to perform a fresh install of Windows 11:

• First of all, back up your personal files to an external hard drive or cloud storage. This step is crucial to prevent data loss during the installation process.
• Download the Windows 11 Installation Media Tool from the official Microsoft website. You can easily find this by searching for "Download Windows 11" on Microsoft's site.
• Create a bootable USB drive using the downloaded tool. Follow the on-screen instructions provided by the tool to create the bootable USB. You'll need a USB drive with at least 8GB of free space.
• Boot your computer from the USB drive. You might need to enter your BIOS/UEFI settings to change the boot order to prioritize the USB drive. This is usually done by pressing a specific key during startup (like Delete, F2, F12, or Esc) – check your motherboard's manual for the correct key.
• Once your system boots from the USB, select “Custom Install” when prompted during the Windows setup.
• Carefully select your system drive (the drive where Windows is currently installed) and choose the option to format it. This will erase all existing data on that drive, ensuring a clean installation.
• Proceed with the Windows 11 installation process, following the on-screen instructions.
• Once the installation is complete, you will need to reinstall your GPU drivers, chipset drivers, and any necessary Windows updates. It's generally recommended to get the latest drivers directly from the manufacturer's websites (NVIDIA, AMD, Intel, or your motherboard manufacturer).
• Finally, reinstall Clair Obscur Expedition 33 via Steam. After a clean Windows installation and driver updates, try launching the game to see if the fatal error has been resolved.

2. Update Motherboard BIOS

An outdated BIOS (Basic Input/Output System) can indeed lead to compatibility problems, especially with newer games built on Unreal Engine (UE) and high-end CPUs. Updating your motherboard's BIOS can often resolve these issues. Here's how to do it:

• First of all, make sure you know the exact model of your motherboard. This information is usually printed on the motherboard itself or can be found using system information tools in Windows (search for "System Information" in the Start Menu).
• Then, go to your motherboard manufacturer’s official support page. Search for your specific motherboard model on their website.
• Download the latest BIOS update file available for your motherboard. Be extremely careful to download the correct file for your exact model.
• Carefully read the instructions provided by the motherboard manufacturer for updating the BIOS. The process can vary significantly between different manufacturers and models. Common methods involve using a BIOS flashing utility within the BIOS interface itself or a dedicated tool provided by the manufacturer.
• Flash the BIOS via the BIOS interface or the recommended method. Follow the manufacturer's instructions precisely. It is crucial not to interrupt the BIOS flashing process, as this can potentially render your motherboard unusable. Ensure your system has a stable power supply during the update.
• Reboot your system after the BIOS update is complete. You might need to re-enter the BIOS settings after the update to configure your boot order and other settings.
• Test the game after the system restarts to see if the fatal error persists.

3. Downgrade or Roll Back GPU Drivers

Sometimes, the very latest GPU drivers, while intended to improve performance, can introduce new bugs or compatibility issues with specific games, leading to crashes like the Fatal Error. Rolling back to a previous stabledriver version can often resolve these problems. Follow these steps:

• Use DDU (Display Driver Uninstaller) in Safe Mode to thoroughly uninstall your current GPU drivers. DDU is a moreeffective tool than the standard Windows uninstall and helps to removeall remnants of the old drivers, preventing potential conflicts. You can download DDU from reputable tech websites. To boot into Safe Mode inWindows, search for "System Configuration" in the Start Menu, go to the"Boot" tab, check the "Safe boot" option, and click "Apply" and "OK."Restart your computer.
• Once in Safe Mode, run DDU and follow its instructions to uninstall your current NVIDIA or AMD drivers.
• After the uninstall is complete, download a previous stable driver version from the official NVIDIA or AMD support websites:
  • NVIDIA users: The suggested version is 552.42.
  • AMD users: The suggested version is 24.2.1 instead of the more recent 25.3.1.
• Install the older driver you just downloaded. Follow the on-screen instructions during the installation process.
• Reboot your computer back into normal Windows mode.
• Once done, try running Clair Obscur Expedition 33 to see if the fatal error has been resolved with the older drivers.

4. Run as Administrator & Disable Fullscreen Optimization

Fullscreen optimization is a feature in Windows designed to improve theperformance of full-screen applications. However, it can sometimes cause conflicts with Unreal Engine-based games like Clair Obscur Expedition33, leading to crashes. Running the game as administrator ensures it has the necessary privileges to run smoothly on your system. Here's how toconfigure these settings:

• Go to the folder where Clair Obscur Expedition 33 is installed on your PC. This is typically in your Steam library folder (e.g., C:\Program Files (x86)\Steam\steamapps\common\Clair Obscur Expedition 33).
• Locate the game's main executable file (usually a .exe file with the game's name).
• Right-click on the game's executable file and select Properties from the context menu.
• In the Properties window, navigate to the Compatibility tab.
• Under the "Settings" section, check the box1 next to "Run this program as an administrator".
• Also, check the box next to "Disable fullscreen optimizations".
• After checking both of these points, click on the Apply button and then click OK to save the changes.
• Relaunch Clair Obscur Expedition 33 and check if the fatal error issue has been resolved.

5. Submit Crash Logs to Developers via Feedback Form

If none of the above solutions work and you are still consistentlyencountering the fatal error, the final recommended step is to submitdetailed crash logs and information to the game developers through their official feedback channels. This provides them with valuable data thatcan help them identify the root cause of the error and develop a properfix in future updates.

Look for a specific feedback form or bug reporting system on the game'sofficial website, forums, or through their support channels. Whensubmitting your report, be sure to include:

• A detailed description of when and how the error occurs.
• Your system specifications (CPU, GPU, RAM, operating system version).
• Any specific steps you were taking in the game when the crash happened.
• Attach any crash log files that the game might have generated. These logsusually contain technical information that can be crucial fordevelopers.

By providing this information, you directly contribute to the process ofidentifying and resolving the fatal error, ultimately improving the game experience for yourself and other players.

Hopefully, by trying these workarounds one by one, you'll be able to eliminate the fatal error and fully enjoy the engaging turn-based combat and theimmersive world of Clair Obscur Expedition 33! Good luck!
