I'm having trouble with an app on my MacBook Air that just won't open. I've tried uninstalling and reinstalling it multiple times, but I keep getting an error message that says: 'Last time you opened {insert app} it unexpectedly quit while reopening windows.' Sometimes it even says 'File Does not Exist.' I'm not very tech-savvy, so I'm feeling quite lost about this issue. Any advice?

Try opening the Apple Menu and using the Force Quit option to close the app. Select the app from the list and force it to quit. If it still won't open afterward, let me know!

I tried that, but the app only shows up for a second before it shuts down again and doesn't stay open.
