Folder List does not update in Linux Desktop Client from vaultwarden afer move from bitwarden to vaultwarden

As said, I had my desktop client (1.26.3) up and running with bitwarden’s hosted server. Some (not too many) nested folders. And the transition to the self hosted vaultwarden 1.21 went with no issues by exporting/importing. I see the folders in the webclient, but in the desktop client the loading spinner goes endlessly. When I click then on the “search entry” field, all entries show but still no folder list.

Any idea where to start looking for the error? Or should I file an issue on github?

Oh thanks for that… I was so sure, that it worked before, but may be I collapsed a folder…
Should have looked there before…
