@barbarad19354805 This is how to fix it (At least for me):
1. Go to Applications/Utilities and find the Adobe AIR uninstaller, and uninstall.
2. Follow this link https://helpx.adobe.com/air/kb/archived-air-sdk-version.html and install runtime version 19 of Adobe AIR.
Done.
(i also had to reinstall my game, but i dont know if u would have to)
