Unity Play Mode starting frozen

[cunning mauve]

Hi there, I'm having an issue where when I hit Play Mode the Game window is just completely frozen. Weirdly too, if I'm in Scene view it doesn't switch over to Game view automatically, nor does using "Play Maximised" work (the window remains small). I've checked out previous git commits and that hasn't fixed the issue so I'm a little baffled. I am getting the error message:

"InvalidOperationException: Collection was modified; enumeration operation may not execute."

but again reverting commits isn't fixing the issue so it shouldn't be anything to do with code. This is happening in every scene.

Update: Clearing the above error did not fix the issue.

You should always first search what the error means https://www.tutorialspoint.com/why-the-error-collection-was-modified-enumeration-operation-may-not-execute-occurs-and-how-to-handle-it-in-chash

I did, I have no code I can think of which should be affecting it, but regardless disabling the relevant object to clear the error did not fix the issue

If you are not sure where illegal operation is happening, you can turn off scripts and introduce them gradually.

But really stack trace should point right at it.
