Hi Marcel,
thanks for the report, it is a bug:
https://github.com/eclipse/sumo/issues/7207
For the most recent libsumo you can download the artifacts from the
github actions see here:
https://sumo.dlr.de/daily/userdoc/Developer/Nightly_Build.html#continuous_integration.
Please be aware to choose the correct python version.

Best regards,
Michael
