Can't connect to local repository

I’m running Kopia server connected to a local filesystem. Today I disconnected the repository for a few minutes. I’m receiving errors when trying to connect to this repositorsy since then. Anyone got a clue what’s going on?

This doesn’t look like a filesystem issue but I’ve started a btrfs scrub nevertheless. Still needs 3 hours to complete.

That looks like some kind of local filesystem problem, some directory has disappeared while the server was running perhaps?

I might have disconnected the repo while the server was still running - not sure to be honest. btrfs scrub did complete meanwhile but didn’t find any errors.

Any chance to repair the repo or debug the issue? Or is this repo damaged beyond repair?
