Because cryptography.hazmat.decrepit.ciphers.modes.CFB are only available since cryptography 47. But Fedora 43 comes with 46  


Reproducible: Always

Steps to Reproduce:
Try to start it
Actual Results:
It crash with "ModuleNotFoundError: No module named 'cryptography.hazmat.decrepit.ciphers.modes'"

Expected Results:
Working app

Additional Information:
See:
https://cryptography.io/en/latest/hazmat/decrepit/modes/
the needed module was added with version 47 of cryptography.
But Fedora 43 comes only with 46.
