Symptoms

The launcher fails to load, crashing with an error about not being able to load gamedata.dat.
Replacing the StardockLauncher.exe binary with AshesEscalation.exe to bypass the launcher lets the game launch, until it finishes loading assets and then freezes.

Reproduction

Replace StardockLauncher.exe with AshesEscalation.exe, launch the game.

Using regular WineD3D11 shows no difference, except for taking longer to finish loading the assets.

Where it freezes;

Review steam-507490.log alongside the reported launcher and game behavior. Reproduce the failure with StardockLauncher.exe, then with AshesEscalation.exe as described; done would mean the launcher loads correctly and the game completes asset loading without freezing.
