Is your lightning node somehow out of sync with bitcoin core?
No idea. It's the problem with these node packages.

Everything is so easy but I'm also reluctant to start playing around in the console.

Been feeling like creating a new lightning node and decommissioning my Umbrel.
In Linux terminal (ctrl+alt+t) shut down your umbrel with this command: sudo ./umbrel/scripts/stop . See if while doing this it produces any errors. Once done, start 8t again with this command: sudo ./umbrel/scripts/start . See if that produces any errors.
I restarted it already.

From the logs:

Looks like it should finish starting eventually. If it still does not after a day - in the old days Umbrel support used to respond to queries in less than a week. They helped me once with a stuck channel. Maybe they still do, try them. Also, chating with chatGPT 4 is not a bad idea. You can ask it how to diagnose, then feed back to it the results of diagnosis, and see where that takes you. But all that is, yes, a console work.
This is the way
