How do I fix a bug where my game keeps crashing instantly when I start it? Btw it's Ben and Ed

Whenever I open Ben and Ed it crashes after a couple seconds and a crash report from UE pops up where I can send report and restart the game but it just crashes again

I have the same Problem with UT. Since today, when i wanted to download some custom stuff directly ingame from the hub it suddenly crashed and now crashes instantly when i start it.

But i cant send a Bugreport cause “You do not have any debugging symbols required to display the callstack for this crash.”

I am having the same issue on UT. Reinstall did not fix. No idea.
