Symptoms
The game doesn't start, nothing happens without black screens, it's visible in Steam that I start playing but the game doesn't appear, and that I've already tried (access rights, Vulkan drivers, reinstallation, different versions of Proton)
Reproduction
Steps to play:
Install Age of Empires II: Definitive Edition on Steam.
Make sure you have the 32-bit Vulkan and NVIDIA drivers installed (e.g. libnvidia-gl-535:i386).
In the game properties, under the Compatibility tab, select Proton Experimental or Proton 8.0-5.
Click the Play button.
Expected result:
The game launches successfully.
Actual result:
The game does not launch, the game window does not appear.
No error message is displayed in the Steam console.
