It may be abnormal but on my machine, if I launch via regular proton and not wine/GE, the game immediately crashes or black screens regardless of tinkering. For future records: Glorious Eggroll's Wine-GE-Latest variant or 8-26 as apparently what the heroic installer says by time of install. Strangely though, the game's ability to run in wine alone suggests that so long as the components are installed through the proper launcher, you could run the game simply by installing your launcher in Wine and then launching from that version of the launcher instead.
