Symptoms

Game takes a long time to start, then the steam launcher fails with the following error:

Image

Trying to bypass the standard launcher via Add a game -> Add non-Steam game -> select NDLAUNCHER.EXE in the game directory, then using proton to launch it gets to the point where the launcher starts and updates the game. Post launch it complains that Microsoft Edge Webview2 is not installed and it opens a website to download it. Installing it via protontricks works, then the game seemingly launches, gets past the gameguard update, opens a window with the splash screen (Joongwon entertainment) and crashes. PROTON_LOG=1 option does nothing in this case, no log is generated (I suspect it's due to NDLAUNCHER instantly handing over to another process for this.)

Reproduction

Launch the game for steam for default or add the NDLAUNCHER.EXE as a non-Steam game, set compatibility layer to Proton and launch it for alternative approach that gets further.
