I had some AI models downloaded, but noticed recently that the AI tab grouping wasn't working. I saw that the models for this were listed as being 0 bytes in size. I deleted all installed models and now can't install any as they always show as being 0 bytes. I'm able to install the models when using a new profile. I have tried in troubleshooting mode and disabling all extensions using my profile normally but neither of these actions have worked. I'm running Windows 11, 25H2, on ARM64, with the latest version of Firefox installed.
