This looks like it's a bug in oscrypto, the library my plugin uses for cryptography stuff.
https://github.com/wbond/oscrypto/issues/78
I can take a look in a couple days and see if I can find a workaround.
Can you post the output of "openssl version" on the command line?
EDIT: Confirmed, bug in oscrypto.
As soon as the system is updated to openssl 3.0.10 or higher the python module fails because they have a buggy regex that only accepts single-digit version numbers. There's not much you can do in the meantime, sadly, other than maybe trying to downgrade openssl again, but that may break your system or other applications.
So this is the same situation as back then when openssl 3 came out, sooner or later everyone will run into this bug.
I'll try to find a workaround asap; and I'll try to find some time soon-ish to finally finish and release 0.1.0 with all the fixes since then.
