Ubisoft Connect launcher broken?

Yesterday I was trying to install the Ubisoft version of AC Odissey on my PopOS! machine, and I wasn't able to do so because when I try to launch Ubisoft Connect from Lutris, it asks me to do the login and then shows only a black rectangle.

I tried looking online for a solution but as far as I understood it's a problem of the new Ubisoft Connect UI and I wasn't able to find any fix... can someone help?

It really sucks because it prevents me to play some games that are supposed to run on Linux just because at the time I bought them on Ubisoft Connect instead of Steam :/
