Hi Shahram509,
Welcome to Apple Support Communities. We understand that you're getting this error message with the Facebook app only.
Since this only happens with Facebook, try the steps from If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open which can help with app-specific issues.
If the same happens after using the guidance from that article, reach out to the app developer for further help. How to contact an app developer can help you locate their contact information if needed.
Take care.
