Game never finishes installing from GOG store

[stemid]

I just got Heroic and wanted to try it with Pathfinder, Wrath of the Righteous from GOG.com, hit Install and it started installing, but never finishes. It reaches 100% and just continues counting ETA all night

Next morning I kill it, and I find the whole game inside the target folder. I can even start it with wine Wrath.exe but I'd rather start it through Heroic with Proton.

But Heroic isn't showing the game as installed and if I try to reinstall it I don't have enough disk space because the game is there already. So now I have to delete the game and maybe suffer the same strange bug again. So is heroic unusable?

OS: Fedora 35

Heroic: From Github releases 2.2.1-1

Nope, it just keeps counting. So a reinstall doesn't help either. Because all I can do is exit Heroic and end the install task before it finishes, so the game is downloaded but it's not playable in Heroic.

Is this a known issue?

I managed to solve the install issue by importing the game after force quitting Heroic launcher when the Install has "finished" on disk, but not in the app task.

The game runs but I can't get past 60% of the first load screen, so I never see the menus.
