Greetings @12_Mok1

Welcome to the Unreal Engine Community Forum! In regards to the error that you’re having I assume it’s only for one project.(If not, post back with info on what all versions it’s occurring on) The first place I’d start is going into your project directory where the Content and Config folders are. Remove any other folders that you have in that directory other than those two. Then test it again. (Note: If you have a Plugins folder, I’d test with it still there and then without it once you remove all of the other folders) Let me know the results of how that works. I hope this helps!

It’s a mistake in game.

Oh, I see! Which game are you having this error in? (Also, can you provide a crash log or screenshot of the error when it occurs?) I’ll be happy to take a look into it for you. Thank you!
