Couldn't read cache at: .cache / Couldn't write token to cache at: .cache

I have unitunes up and running. It seemed to install without any issues. I have added my spotify client ID, secret and redirect URI, as well as the youtube headers. It seems to pull the song okay from both platforms and reflects the correct number of songs. Unfortunately, when I try to push a playlist, I get a long list of the same two errors. The songs don't seem to be migrated between services. The errors are as follows:

Couldn't read cache at: .cache
Couldn't write token to cache at: .cache

I'm on macOS 13.4, python 3.11

Does anyone have any idea what is going on?
