I’m trying to add the HACS integration in HA os 2024.9.1
After added the HACS files I receive the error on Add integration.

How is HA installed?

Home assistant system on Proxmox VM

Ok, it is not a HA Core (vevn) installation with missing dependencies, so I’m at a loss here. Did you restart HA?

yes; I tried the integration add process and I receive the error message

Config flow could not be loaded: {“message”:“Invalid handler specified”}

It’s frustrating it is not possible to use HACS… I don’t understand why but I think an installation config issue
