object has no attribute 'FwUnit'

While tinkering with Bullseye on one of the boxes in the studio I ran across the following when launching hinawa-apogee-duet-cli.

Traceback (most recent call last): File "/usr/bin/hinawa-apogee-duet-cli", line 6, in from hinawa_utils.oxfw.apogee_duet_unit import ApogeeDuetUnit File "/usr/lib/python3/dist-packages/hinawa_utils/oxfw/apogee_duet_unit.py", line 6, in from hinawa_utils.oxfw.apogee_protocol import ( File "/usr/lib/python3/dist-packages/hinawa_utils/oxfw/apogee_protocol.py", line 141, in class InputCmd(): File "/usr/lib/python3/dist-packages/hinawa_utils/oxfw/apogee_protocol.py", line 274, in InputCmd def get_meters(cls, unit: Hinawa.FwUnit): File "/usr/lib/python3/dist-packages/gi/module.py", line 123, in getattr raise AttributeError("%r object has no attribute %r" % ( AttributeError: 'gi.repository.Hinawa' object has no attribute 'FwUnit'

It had worked in the past with Buster. Any ideas as to what would cause that?

Installed packages: gir1.2-hinawa-3.0/testing,now 2.2.0-1 hinawa-utils/testing,testing,now 0.2.0-3 libhinawa-dev/testing 2.2.0-1 libhinawa2/testing,now 2.2.0-1 python3-hinawa-utils/testing,testing,now 0.2.0-3
