Bug Issues with Unity Hub

After a recent Windows update Unity Hub has started to act very strange.

• I need to open the Hub twice for it to actually appear
• When opening a project from Hub I get a pop-up: "To use Unity, you must have an active license. Please download the Unity Hub and activate your license" (options: install or quit unity). I have a license.
• After pressing "Quit Unity" and opening the project again it actually opens, but I'm logged out in the editor and when pressing Account > Sign in I get "You must install Unity Hub to sign in and use Unity services".
• When going to the "manage license" section of Hub and pressing "check for updates" it never finishes checking.
• When logging out of Hub and then trying to log in again I'm greeted with an empty white window and nothing else.

What I've tried:

• Reinstalled Hub
• Restarted computer
• Checked firewall
