i have looked through the comments. i did follow the steps you provided to another person with a similar issue.
i had comfy and it didn't work (deleted it as well as your app to do a hard restart of the entire install process, just to be safe)
to put it into steps, i downloaded the main app and the addons/mods available on the itch app, went though with going through like that for a bit, downloaded comfy, which didn't seem to do anything at all, even after following your advice to the other person. i do have rather limited storage, and idk which between comfy and stability is smaller
and that should be it, i didn't exactly try for long
