Blocked at "loading" screen - how to reset the app / cache ?

After playing a bit with the app, it now stays in "Loading" state at startup (see screenshot)

I tried to remove the cache in `~/Library/Application Support/hf-diffusion-models` but it just cause a re-download.

How can I reset the app, delete all files created and start like on a fresh machine again ?

Alternatively, how can I pass the "Loading" screen ?
