After installing UnityHUB in Linux gray big box open

I have installed the latest version of UnityHUB in a Debian machine, all went good but after the installation, when I try to open the app I just get a Blank box and nothing happens, it is even difficult to close that.
No erros, no warnings, no logs, nothing… UnityHUB looks like Windows errors “an error has occurred” genius!!!

Sorry but I’m frustrated…

Sorry to hear you’re having trouble.
Could you please specify which version of the Hub you’re using? Is it the latest V3?
