Hi,
By the traceback you are quite close to master.
The issue you see is really strange.
I would try to debug it manually, like starting a python shell and doing the same import and playing with the pythonhome for example as it was suggested.
I usually use Ubuntu20 for my test envs and never seen such issue with devstack.

Regards
Lajos
