Symptoms

Installs, creates a Windows sub-directory, prepares it for the game, then tries really hard to do anything but crash.
Then crashes.

Reproduction

Reinstall the game.

Additional information

Logs are talking about:
LogWindows: Failed to load '../../../Engine/Binaries/ThirdParty/PhysX3/Win64/VS2015/APEXFramework_x64.dll
And many more .dll files from the same directory. Those fail right before:
LogCore: Engine exit requested (reason: EngineExit() was called)

It seems that the physics engine is unable to load up since the files seem to be missing, so calls the game to shut down. Even though all the other files are clearly loading up as expected.

Yes, the files are indeed where they should be when I checked for them.
And yes, I did reinstall/verify the game.

Every other game using Proton/Vulkan works happily and well.
I have uninstalled this game a week ago, yet reinstalled when the update dropped, which wasn't supposed to change much.
