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.
