I have been given a potential fix by the lemmy devs to be able to update to 0.19.12.

https://github.com/LemmyNet/lemmy-ui/issues/3206#issuecomment-2994482703

I will attempt this fix sometime soon and if it fails revert a snapshot again, or if it succeeds post that we are up to date after. Will be in the next couple days sometime.
