:sweat_smile: I seem to have fixed it with e2ee decrypt --retry-failed-items. Error message is below anyway, in case it helps. Thanks, Laurent.

One or more items are currently encrypted and you may need to supply a master password. To do so please type e2ee decrypt. If you have already supplied the password, the encrypted items are being decrypted in the background and will be available soon.
You may also type status for more information.
