Storyboard Pro 20: Audio Error, Missing audio files


I keep having the issue of audio files going missing. I’m editing a storyboard project by importing audio clips and changing timings, and suddenly I get this error message:

I went to see the project’s audio folder, and all of the audio files are suddenly gone from there too. Reopening the project or computer doesn’t solve this, the files are simply gone.

Does anyone know what’s happening and how to avoid this? I also had problems of all the panels going white at the same time. I’m new to the software, so I don’t know if I’m doing something to break the project. Didn’t see any others writing about the same issue before either.

Storyboard Pro 20
macOS Big Sur 11.5
6-Core Intel Core i5, AMD Radeon Pro 5300 4 GB

I use 6 audio tracks, audio clips are mostly .wav but there are .mp3 clips there too unfortunately.
