Got around to reinstalling the game after completely wiping my system. At first the launcher wouldn't even work using GE, so I switched to proton beta. Launched to the launcher, went through log in, then fired up the game. Nuthin, just a black box. Went to proton 7 (due to other reporting potential fixes), game laucnhed and showed intro cinematic, then showed a loading screen before character select and froze. Wiped the prefix and went to experimental, same thing. Props to the game devs for borking a game that ran almost as well as the windows version.
