When I first click to load Unity Hub, nothing opens (and nothing in my task bar), but it shows in Task Manager. So if I click open again, it just sits on the following screen. I've left it there for over an hour, no change. I've restarted my PC. I've checked my firewall. I've deleted the Unity Hub folder in my docs. I've fully uninstalled it with Revo Uninstaller. I've tried the latest version. I've tried the beta version. Nothing works. I also can't use the package manager if loading a project directly.
