Thanks for reporting. This strange error is also reported in https://github.com/audeering/audb/issues/240 and https://github.com/audeering/audb/pull/239, see also the failed CI job at https://github.com/audeering/audb/actions/runs/3765104243/jobs/6400231551.

We have an idea what might be the underlying issue, but we haven't solved it yet.

As a workaround you could use Python 3.8 or 3.9.

We have now released audb 1.4.2 which should solve this issue under Python 3.10. Could you try to run

$ pip install --upgrade audb

and rerun your command again?
