I got the game through the Ukraine bundle and I've been playing it on Linux (through the proton compatibility layer; I've got a steam deck) without issues -- but whenever i reach the Overpass zone in Maroon Valley I'm hit with this message

And I can't go on or do anything but restart the game, and then the bug just repeats. Is there any way to fix this without losing my save? I'm absolutely loving the game, but I'd hate to lose over 12 hours of progress.

Did you ever figure out the solution to this problem? I've tried emailing them, but got no response.

I seem to be able to get it to run with the linux version, but it shows mouse and keyboard contrlls. Did you guys get the game workin in a good state?
