The good news is that the Last Epoch developers are aware of this disruptive Unity crash error and have confirmed they are diligently working on a permanent solution. The less encouraging news is that there's no definitive timeline for when this official patch will be released. It could be hours, days, or even a week. While we await the official fix, these troubleshooting steps offer a strong chance of resolving the issue for you:

1. The Classic Restart:

The first and often simplest solution is a full PC restart. If you're encountering the Unity error and can't log in, begin by completely restarting your computer.

  • Right-click on Last Epoch in your game list.

  • In the Properties window, go to the Installed Files tab.
  • Click on the Verify Integrity of Game Files option.

Steam will now initiate a scan of your Last Epoch installation, identifyingand repairing any corrupted or missing files. Allow the process tocomplete fully. After the verification is finished, try launching thegame again to check if the Unity error has been resolved.
