subscription-manager fails with cryptography error in RHEL 8.5

Latest response

I accidentally deleted my system from the redhat consumer portal that linked it to my developer subscription.

According to the instructions, the way to get it back was to issue the "subscription-manager register --username myuser --password mypassword --auto-attach' command.

The problem is that I receive an error anytime I use subscription-manager with the register command:

[root@ares ~]# subscription-manager register --username myuser --password mypassword --auto-attach
module 'lib' has no attribute 'Cryptography_HAS_TLSEXT_HOSTNAME'
[root@ares ~]#

Any suggestions for how to make this work?
