HACS error Integration not found

I hope this is the correct place to post my problem with HACS. I’ve had HACS installed for a few years now. It’s been working fine up until recently. But now I’m getting an error:
Home Assistant Core
Setup failed for hacs: Integration not found.
9:21:21 PM – (ERROR) setup.py

Does anyone have any idea what this means? Which integration is not found? Any assistance I can get to resolve this error would be appreciated. I want to install the new media manager so I can start streaming to a network speaker, but i can’t install that till I get HACS working again. Thank you!

Have you tried re-running the HACS installer to update it? It could be that you have a very old version of HACS you forgot to update.

Thank you for this suggestion. I uninstalled and re-installed HACS and that seems to have fixed it. Your help is much appreciated!
