Cannot open project in v5.3.2 , "An Unreal process has crushed" - how to fix?

Hi guys,
I’m unable to open a project for some reason. It was open and saved yesterday, and today I keep getting a Crash Report. I can open other projects, so the issue is in this particular project.
Here’s the summary of the report, if someone knows what this means:
