Sorry, something is wrong! check50 ran into an error.
Please let CS50 know by emailing the error above to [email protected].
However, that does not happen when using the --local flag, like so:
check50 --local liv-ac-uk/COMP108/2020-21/A1
In that case the check proceeds as normal.
This problem is present when using CS50 IDE terminal and also my own system.
I'm having some trouble replicating this issue for myself:

From the stack trace you shared, it looks to be a git commit that is failing somehow:
_run(git("commit -m {msg} --allow-empty", msg=commit_message))
But for reasons unknown!
Could you try running check50 --log-level debug liv-ac-uk/COMP108/2020-21/A1? This should hopefully tell us why git is failing to commit.
Here is the output for
check50 --log-level debug liv-ac-uk/COMP108/2020-21/A1:

I've noticed your check50 output says generated by check50 v3.1.2 while the version on CS50 IDE is 3.2.0.
@YalesRios I think the reason this is failing is because you have a branch in your me50/YalesRios repo called liv-ac-uk/comp108/2020-21 already, which is a prefix of liv-ac-uk/COMP108/2020-21/A1 and git doesn't allow branches to be prefixes of other branches. You can get around this by renaming either branch such that none of them is a prefix of any other branch or simply deleting the prefix branch.
I've gone ahead and renamed the branch for you to old/liv-ac-uk/COMP108/2020-21/A1, so I think you should be able to run check50 now without any issues.
@Jelleas thoughts on how to address this better? Maybe a better error message and offer to rename? Would that break anything?
@kzidane agree, we can do better here. Would just need to check for a prefix-branch, and warn and exit. Anyway, this would live in lib50, so let me just open up an issue there and link this :)
