Problem with cryptography lib 43.0.3

[Gellimer989]

I was using Python 3.9.1 together with the cryptography library version 43.0.3. When running the application, I encountered the following error in the console:

TypeError: Using ad-hoc certificates requires the cryptography library.

This error appeared to be related to the use of ad-hoc certificates. To resolve the issue, I downgraded the cryptography library to version 41.0.3, after which the error no longer occurred.
