Pop_OS/linux Vocals/Accompaniment tab throws errors.

Terminal displays this error when trying to extract audio:

/tmp/gradio/c86795c1217b83227cf6fe6afb93bb1dd75ed5ee/NineInchNailsAllTimeLow.wav: No such file or directory

Even though that path and file do exist.

Webui displays this:

Does anyone have any advice?

Start by reproducing the Vocals/Accompaniment tab failure, then inspect infer/modules/uvr5/modules.py and infer/modules/uvr5/vr.py around the reported audio-loading calls. Compare the existing /tmp/gradio input path with the TEMP path used during processing. Done means an existing audio file can be extracted without the reported FileNotFoundError.
