Stops working after 10-15 minutes
Version 21.5.1
When using InDesign after about 10-15 minutes, I can still see my file but I cannot do anything: I can't change anything, can't add anything, it's completely frozen. The pointer still works and can move about the page. I can click on buttons but the drop down menus don't come down, and I cannot close the file even with shortcuts or close down InDesign. I have to End Task in order for it to close down. This continues to happen repeatedly.
Expected Result: InDesign should not be hanging up and forcing me to Force Quit in order to try to hobble along.
Actual Result: InDesign is hanging up after 10-15 minutes where I cannot proceed to do anything in the software.
