Hey @MTLPGaming , thank you for your response - and happy holidays as well!
I successfully installed the editor using this developer’s CLI script. Here’s the post I found it at. I have tested it and installs correctly on Windows.
Regarding your issue, last year I attempted to install Unity on the Steam Deck, which uses Arch Linux as its operating system. I encountered the same issue when trying to log in with Unity Hub. my memory is somewhat rusty, but I recall having to download additional packages via pacman to enable Chromium to redirect back to the Hub with the proper authorization. Sorry if I can’t be more help.
