I got same problem, too. and I believe that might because the game has a rag launcher.
For that I just run "Kowloon_Game.exe" in game filed, it can run the game and got achievement well but ingame screenshot.
BTW, you can open "UserConfigFile.ini" to adjust resolution and input setting.

thank you for answer. I will try.

Did this work for you cause it still doesn't work for me.
