I would attempt to run the following command:
cp /opt/qradar/lib/perl/Q1/auCrypto.pm /opt/qradar/lib/Q1/
These errors occur more commonly in older QRadar versions, but can occur elsewhere. I would run the copy command listed here, then try to reset your password.
If you are stuck or continue to experience the issue, open a new case for us to investigate. If you are locked out of your appliance, you should set a high severity on the issue so you can continue to administer your appliance.
