Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

I put in a solution that the "hint" AI deems correct, but there's a hidden import that is preventing me from submitting the problem.
It gives this same error even if I reset the code and submit with no changes, so I think this just happens with any submit.
