"Measure app not working: My measure app is not working on my iPhone 12 Pro Max. The level still works but when I try to use the measure feature the screen is all black and the options are all greyed out. I’ve tried to force restart my phone to close and re open app and to delete and redownload and it’s still won’t work.I also have updated to ios 17 but it’s still not working."

Reset to Factory Settings:
Being this is a builtin app, and you have been having issues with it for a bit, I would consider backing up the iPhone, and then reset your iPhone to Factory Settings. Go here: How to Factory Reset your iPhone, iPad, or iPod touch - Apple Support
IMPORTANT: Be certain to create a backup of your iPhone prior to bring it in. That way, you can have something to restore your iPhone from, should anything go wrong after the reset.
