Unable to deactivate one of my two licenses for Studio 2019

I am running Studio 2019 SR2 - 15.2.8.3007

I need to return one of my two licenses in order to reinstall and reactivate Studio on my computer after some hardware upgrade.

The Deativate button doesn't work and if I try the offline Deactivation, after I generate the Deactivation authorization, the system can't generate the Certificate, it gives an error.

How am I supposed to return my license?
