My UE4.19.2 Crashs all time

My UE 4.19.2 Crashs all time. the program crashes after 1 minute of use in all of my projects. I have already reinstalled and would like to go back to version 4.19.1

Mine crashes at compile and the project never opens again. It’s weird because I make minor changes between compiles. I have no idea what’s going on. That’s why I’m going back to 4.18 because I cant even rollback to 4.19.1!

maybe you computer is slow
