step to reproduce the issue:

- on macos, plugin key A,
- create backup, then unplug A
- plugin key B, then restore from the backup
- run `onlykey-cli credential ls`, then got error below.
- unplug key B, plug key A, run `onlykey-cli credential ls`, then also got error below.

```

everything else works without problem with key B.  
I can use it to ssh/fido2 login etc..
