OK, I updated to InDesign v. 16.2.1 last night--this morning it will not go any further than the display screen (see below). Then I get the dreaded beachball of death. I deleted pref files, cache files, etc. but to no avail. So I uninstalled, and went back to v. 16.2.0 which was working fine yesterday. But now, it is not--it is doing the exact same thing as 16.2.1. And of course, I am on heavy deadlines. I have turned off/disabled fonts but that doesn't seem to have any effect either. Can anyone help me????
