Steps to reproduce the error

• systemctl --user start offlineimap-oneshot.service

I think it might be because of the localized name Gelöschte Elemente that got mapped to Gel&APY-schte Elemente in former versions. But I don't know why that should have suddenly stopped working.

Workaround is deleting the folder from the local mailbox, and from the offlineimap cache. After that the sync continues to work fine.

The other way might be to try the still experimental utf8foldernames configuration option.
