'NoneType' object has no attribute 'add_job'

This is something I seem to start seeing now that I updatet do HA 2022.12(.6) during start of HA:

Does this happen on every start? I haven't been able to reproduce with 2022.6.2 thus far, but upgraded only yesterday.

I monitored it for a while (meanwhile on HA 2022.2.9) and did not see this again. Therefore I'll close this for now, only turning back if I see it again.

Same thing happening here with HA 2022.04.6
