I believe it's not exactly something that I can do. Either Windows 11 needs to do some sort of update to their OS to make Unreal Engine games run proper 100% of the time, or a newer version of Unreal Engine needs to be made that can support Windows 11. So unfortunately either way, there's nothing I can really do since I can't be updating AtC to a newer version of Unreal Engine and we can only hope it's something Windows 11 can fix through an update to their OS.
