[2021] Game Closes without any error??

Make sure your antivirus and Windows Defender (if on Windows) has cities.exe listed as an allowed/trusted app.

If that doesn't help, we'll need the output_log.txt to see what's happening. I recommend posting on the official support forums, so we can look into it. Steam just isn't great for support as you can't attach files here.

Strange! The link I posted takes me to the correct place, where yours lands me at the CS general forum.
