Qubes Template Manager (UI) constatly failing

the error is Error 13 Permission denied ‘var/qvm-template.ick’

i didn’t make any modifications to dom0, when i open the regular ui / app of template manager and try do anything like install, it fails with that error each time with any kind of action or template, existing or not.

seems like the only solution is running qvm template manager using sudo, but i rather not do that, I’m not sure what happened nor how my policies got corrupted, maybe it’s only an issue with that specific app?
