Hi there. I’ve been using different versiones of UE4, the last one being 4.16. Recently I installed the 4.21.1 version and was working without problems, but the engine suddenly crashed when trying to save a project. After that point, I was unable to make the engine start again. This is the report:

This started happening also with 4.16, and after that I tried with 4.18, 4.12, 4.14… I uninstalled every engine and even de EpicGames Launcher. Nothing works, I just can’t make the engine to start again. I’m working on a Macbook Pro with the following specs:
