Hi there! I see your Prison Empire Tycoon app is freezing and closing right after you open it on your Mac running OS X 10.15.7. Let's try to get this sorted out together.

First, could you tell me if this started happening recently after an update or any changes to your system? Also, have you tried closing other apps running in the background?

Meanwhile, here are some steps you can try:

1. Close Background Apps: On your Mac, close any unused applications to free up memory that might be causing conflicts with the game.

2. Restart Your Mac: A simple restart can often clear temporary glitches.

3. Check for Game Updates: Make sure the game is updated to the latest version available on the Mac App Store or the platform you installed it from.

4. Reinstall the Game: If the above steps don’t help, try uninstalling and reinstalling Prison Empire Tycoon to ensure all files are intact.

5. Check Disk Space: Ensure you have enough free disk space as low space could cause apps to crash.

6. Permissions and Security Settings: Sometimes, macOS permissions can block apps. Go to System Preferences > Security & Privacy > Privacy, and make sure the game has the necessary permissions.

If after these steps the issue persists, please let me know if any error messages appear, or if the app crashes at a particular point during loading. That info will help diagnose further.

Are you comfortable trying these steps now?
