HAOS 11.5 Upgrade caused hectic boot loop

I upgraded my NUC installed HAOS from 11.4 to 11.5 last night and it got stuck in a hectic boot loop, restating every minute or two.

The HA log has nearly 3000 lines in that one or two minutes ending with this:

asyncio.exceptions.CancelledError: Final process shutdown

Unfortunately the Supervisor log doesn’t get a backed up copy from the previous boot so the current one has no errors at all.

It took many restarts / power cycling to get it to stay alive. Anyone else has issues or know what could have been the issue?

It should revert to the previous version after three tries.

Suggest you open a new issue here:

I’m happy to report an issue there but without a Supervisor log showing what was going on at the time I have no evidence to work with… While it was happening I couldn’t get access to HA to investigate.
