OSError: Cannot load native module 'Cryptodome.Cipher._raw_ecb'

It seems that after an upgrade I am unable to run weechat-matrix. Happy to provide more details.

Seems like the pycryptodome install is broken somehow. Interestingly the self test doesn't fail, are you sure the same version is running inside of Weechat?

Yes, I restarted Weechat to test it and again the self test succeeded.

This was an issue related to an incorrect Python version Weechat was running.
