If you're having trouble opening games on your computer, there are a few things that could be causing the issue. One possibility is that your computer's resources are being taxed by other programs and processes, and as a result, it doesn't have enough power to run the game. Another possibility is that the game itself is incompatible with your system or has some sort of error.
To troubleshoot this issue, first make sure that your computer meets the minimum system requirements for the game. If it does, then try closing any other programs that might be running in the background and see if that solves the problem. If not, try reinstalling the game or contacting the developer for support.
