InDesign opens but nothing works on second monitor
I'm using a MacBook Pro M2 attached to a LG 40WP95C-W monitor running Adobe InDesign version 17.4 on Mac OS Monterey v 12.5.1.
All the other Adobe apps work fine on the second display but InDesign only works on the laptop screen.
What happens:
After trying everything listed below, I'm at the point where the application will open and display the start screen, but none of the buttons on the screen work. The menu dropdowns don't drop down, or they make a vague outline of the dropdown but no text appears.
Here's what I've tried and the result:
Change monitor scaling (Tried 1920x1080, 4608x1944 and 5120x2160) - no effect
Turn off "Use GPU settings" - no change
Delete Application Roaming Data and Local Cached Data folders - no joy
Opening InDesign on laptop screen and then switching to 2nd monitor - crashes instantly
Uninstalling and reinstalling InDesign - no change
