Project crashes on start-up

On opening my project it crashes. While I was working on my project, it randomly froze and refused to unfreeze so I closed it. On reopening my project its crashes around 54% when loading, I hadn’t really done much in terms of changes so I’m unsure what has caused the crash. I can’t figure out what it is from the report.

The crash report is below.
