Cannot create a record in a specific module

I am getting an error of “not found” when trying to create a record in a specific module I have made. This error occurs whether I am using workflows, the UI, or the API. I can create records without issue in other modules, just not this one. I have tried deleting the module and re-creating it (using the same name), and I am still getting the same issue.

Thanks in advance!
