Ok, managed to fix mine.
I have the Appdata backup plugin. I deleted the docker, restored it to a backup from 25/12/23, and redownloaded the docker with forcing it to version "3.0.10.1567-ls218".
I noticed that version was issued ~2 weeks ago, and the latest version from ~2 days ago is some 4.XXX version. Looks like the corruption must have happened with the new main version #. Looks like i'll be sticking with forcing the current version to be safe!
