I am running CC on Mac OS 10.14.3 and after updating Illus CC to 23.0.2, Illus just won't open my files or start new ones. A document or illustrator screen is hidden and I can see it partially via a strip on the right side and bottom to the underneath layer. However, the progress wheel just turns and turns, and I have no access to toolbar or any way to fix the situation. I cannot use any of the tool bars or top menus.

I have tried restarting the app, uninstalling and reinstalling twice, restarted computer, etc.
