Ive seen 1-2 people experience this, so Ill say it. The game loads, white screen, then black screen. I finally decided to do a bit of research after trying to play this game on and off for a year or two.
So, the problem is that the game is broken. When the game loads and you press F12, you can activate Devtools. This reveals a multitude of errors and warnings, causing the game to fail to load, hence why the game never loads no matter how long you wait. Very unfortunate.
