4.25 OS X crashes on opening project

Hello. My project was working fine yesterday, I restarted and today UE4 crashes as soon as the project tries to start. Other projects seem to start except this one. I’ve tried going back to previous versions of the project using GIT but same result. It seems this project might have become corrupted somehow.

I’ve also tried disabling metal by commenting out the appropriate line in ConsoleVariables.ini as I read in a post.

Some instability was introduced when I updated my OS X version to Catalina 10.15.5.

This is my main project. Any help would be greatly appreciated.

The logs state the following:
