Unreal Engine 5

One of my UE5 projects keeps crashing before opening and I was wondering if you know how to fix it? Below is the info that the system is providing. It seems by removing that corrupted file(s) it should work again, but I don't know how to fix that.

Do you have experience with what you see below and would you be able to help me, please?
