Eye dropper does not work well

1. Go to the Apple menu > System Settings > Privacy & Security > Screen Recording (this may appear as Screen & System Audio Recording, depending on your macOS version).
2. Locate Adobe Premiere Pro in the list:
   • If it's unchecked, select the checkbox to enable it.
   • If it's already checked, toggle it off, then back on.
3. If Premiere Pro isn't listed, click the + button and add it from Applications.
4. Quit Premiere Pro completely, relaunch it, and test the eyedropper again.
