Problem is solved.

I had to configure HACS and check the box…
Then reload.

What caused this change?
I did not update anything recently, how can a change like this suddenly effect the complete dashboard?

I thought as long as we do “not touch a running system”, it will always run same.

Did you mean you had to tick or UNTICK the box?

In my case HACS no longer loaded after updating HA CORE to 2025.1.1 and I noticed that an update for HACS was also pending, 2.0.2 and not sure if that was needed for new HA version?

I had to to UNTICK that box for HACS to load fine again and the HACS update came up for 2.0.2 and after updating to that I ticked that box again and loaded fine after restart. (so it seems it doesn’t load with it ticked in the new HA core version).

FYI there is an issue on github but comments are currently locked to contributors lol

I also had this issue after updating home assistant to the latest version — hacs stopped working. I found three separate issues reported about this on GitHub for this particular version but they were all closed by the developers. One of the issues even had 16 thumbs ups, seems like lots of people having this issue.

I can’t find anywhere a warning that this changed and this box needed to be checked on upgrading home assistant. Not sure why this is being so user hostile.

This broke my whole dashboard when nothing was updated or changed for weeks on my end, and then with the developer closing issues and locking comments it made it so hard to find out what’s going on! It wasted so much time when it shouldn’t have, and I just don’t get the developers mindset at being so hostile to people posting issues? Hacs just suddenly fails to load, 16 other people thumbs up the github issue, and then they just close and lock comments will no help offered. Pretty ordinary response to people having issues… Thank you to those above that took to the time to post a fix.

I also want to understand why the developer closed and locked the issue. I had the same problem and found the lack of information on the GitHub issue very frustrating: HACS 2.0.1 Failed to set up · Issue #4325 · hacs/integration · GitHub

not only that, the only other reply besides the guy who closed the ticket is a link to here which actually solved my problem, is marked as off topic!

Thanks for the solution!

I didn’t update Home Assistant and am still on 2024.12.5. All I did was update NWS Alerts to the newest version, restart HA, then HACS was dead. Wasn’t sure if the NWS Alerts broke it at first, which seemed weird. Glad this seems to be an unrelated issue and just odd timing.

I had the same problem and after clicking on that button from the solution, suddenly 2.0.2 appeared. But now I’m facing the “problem”, that inside HACS, only hacs is installed, not any other of my components.

When I check the devices, I can see the services.

Is this a problem regarding updates of these applications? I tried to reinstall Bambu Lab for testing and it seems that it didnt cause a problem…

Does anybody of you have any idea if I have to reinstall all applications now to get this working again?

Thank you!

Solved by restore hacs.properties backup.

For clarification for future people:

I had to install HACS again (not sure why it ended up being removed after the last update) then I went into Settings > Devices and Services > HACS > Configure > deselect “Enable AppDaemon apps discovery & tracking” (I enabled it previously but restarted HA instead of reload and it did not fix things) → Submit → hit the three dots button near “Configure” and select “Reload” → do the same thing but now ENABLE the “Enable AppDaemon apps discovery & tracking” setting, and reload once more.
This fixed everything for me.
