Problem with activating Studio 2019 on a new computer

Hello,

I'm moving to a new computer. I have deactivated my studio 2019 licence on the old one and as the online activation on a new computer didn't work (couldn't connect to the activation server error), I wanted to use the offline activation but the Licenses page froze when I tried to generate the activation certificate. When I refreshed it, it shows the license as in use, even though I didn't get the activation certificate, so couldn't activate the Studio. Could you please help?
