Screen Flickering Issues in InDesign on Mac with External Monitors

For the last week, I have noticed that my screen flickers when working in InDesign. As I click within the document, the screen will flicker, and at times, it goes completely black.  I have 2 external monitors, and the flickering happens on both monitors.

I have read through the forum and tried turning off the GPU Performance in preferences, but that only made things worse. I also tried turning off the page ruler and that made no difference. Finally, I updated to the latest version of Sonoma (14.6.1) in case there was a bug fix. Nothing has worked.

Please help! I work in InDesign 95% of my day and the screen flickers are giving me headaches - not to mention incredibly annoying.

I have a Mac Mini

Apple M2 Pro

Sonoma 14.6.1

Both monitors are:

ASUS ProArt Display PA278QV Professional Monitor - 27-inch, IPS,
QHD (2560 x 1440), 100% sRGB, 100% Rec. 709, Color Accuracy
ΔE < 2, Calman Verified, ProArt Preset, ProArt Palette

InDesign 19.5

Thank you for your help!
