Error: "System service failed" after updating


after searching a lot here and trying different things I need to get help on my specific problem.

A few days ago I started the update from my mobile device. Afterwards I’m just seeing the error message " Error: System service failed " when I’m connecting to umbrel.local.

I’m able to connect via SSH and got from there the following logs:
(I had to use paste bin since 0bin was just not saving my paste and pasting here was not possible).

I tried to find any issue in there, but since I’m not a programmer I didn’t see something specific.

Maybe you can help me?
Thanks in advance!
