Error in automation after update

Configuration
1

Hi,
I am running Home Assistant OS, Core 2026.1.3, Supervisor 2026.01.1, Operating System 17.0 and Frontend 20260107.2
After an upgrade of the Core, the automation is broken. I think this is the root-cause for some other integration fails, e.g. Shelly.

I do not know where to look for to get the error fixes, pls. help me, my system is not working any more!

KR,
Christof

No, this did fix another issue, but not this one. The logs still show multiple errors, all of them look the same:
