Cannot sign in to Unity Hub

Hi,

I wasn't able to sign in to asset store from within Editor. It asked me to download Unity Hub, even though it is already installed.

I logged out from the Unity Hub, deleted it and reinstalled it.

Now I can't log in back again, the sign in pop-up window is just white.

I was away for 2 years from game development and it's sad to see the quality is not improved even at the beginning. Also I wasn't able to download the Unity from withing Unity Hub, I tried 4 times. Finally my solution was to download it via torrent.

I tried setting 2 environment variables, which I saw on another thread of the forum, but it didn't help.
