Windows 10, using Firefox 145.0.2. I do see the loading screen, but after that is just a snow covered area and clicking around does nothing.
That's very strange - That's pretty much my own setup. You should see a main menu with some buttons on the top left...
I will look into options how to get error reporting in, so maybe i can learn that way what is failing on your system.
I recently pushed a fix, it might fix the issue you saw. Please give it a try if you can :). And if it still crashes, at least I will get an error log that helps me fixing it! Thank you in advance and wishing you Happy Holidays!
Seems like it's working now!
