HACS integration issue

I have an issue when I try to include HACS into my RPI4. It used to work before updating to 0.104.3, but now every time I click integration -> HACS it goes back to the list of integrations. The HACS team says it is an issue with homeassistant, but I honestly don’t know what to do to fix it.

Below is the error log. HACS team says it happens before HACS is even called. Everything else works, except HACS and I don’t want to have to start over at this point.

If all you did was update to 0.104.3 you don’t have to do anything. HACS should still be there.
