I'm pretty sure, no 100% that Keyboard Maestro culprit. Guy use that? Yes fine for 10 years... now mayhem... Catalina or Word..?conflict?
I am using Keyboard Maestro with Catalina 10.15.5 and do not experience what you are.
I have followed your other issues with Catalina and I am thinking the problem may be with your Catalina installation. How about a clean install?
