Whenever I share anything to Facebook from my phone, be it a WORDLE results from my NYTimes app, or a webpage on Chrome, whenever I hit the share button, and I get the Black Screen, it gets stuck and I cannot do anything except reboot my iphone. Please someone, help!

I just figured out what to do! My Facebook app (and more) was not updated. Once I updated my app, the problem went away and shared to Facebook began to work properly. Open the App Store. Tap your profile icon at the top of the screen. Scroll to see pending updates and release notes. Tap Update next to an app to update only that app, or tap Update All.
