Still occurring as of latest Experimental build on oled
What seems to be happening is that, for some reason, the launcher changes directory to Moto Racer Collection/MotoRacer, but it runs MotoRacer.exe from the Moto Racer Collection directory, which is just the launcher again but now it doesn't work because it has the wrong working directory.
Retested with proton Experimental and it seems for Moto Racer 1, it's not tossing the exception anymore, I press play, confirm English as the language i want to play in, then it silently crashes.
Moto Racer 3 still has the same white screen issue.
Moto Racer 1 launches with Wine 10.6 appimage on Steam Deck after "Emulate a virtual desktop" in winecfg is selected with 1280 x 800 resolution but the game window is a small 640 x 480 resolution box in the top left hand corner of the screen.

Symptoms
Trying to launch Moto racer 1 fails on deck, when you hit play it jumps back to the launcher, then tosses up an error log saying it couldn't find the game or something if you press play again.
And Moto Racer 3 seems to get stuck on a white screen.
