First, restart your console. This can help to reset the game and fix any minor bugs and glitches. If you are playing on a PC, simply shut down and restart your system.
Once your console is restarted, make sure that the game is up-to-date. Many of the bugs in Apex Legends are caused by outdated versions of the game, so it’s important to keep your game up-to-date. You can do this by checking for game updates in the game settings.
Once your game is up-to-date, you should be able to access the Imperial Guard event without any problems. However, if you still can’t access the event, you should try not to open any regular packs until you have fixed the issue. This will ensure that you don’t lose any of your progress.
Once you have ensured your game is up-to-date and you’re not opening regular packs, you should check the game’s official social media channels for any updates or news about the bug. This will help you stay informed on any changes that are being made to fix the issue.
