And just like with you, everything else seems to be fine.

Have you found a solution yet?

Got it sorted out. Problem was a single repo which had a custom post-update hook. The hook did a checkout to a directory which had been deleted. Removing the hook or creating the directory again fixed it for me.
I was able to access single repositories before by manually entering the URL, but this very specific one would give me a 500. Pushing to this repo gave me a proper error message and allowed the fix.
