Cannot open schematic

In several of my designs I cannot open or navigate in schematic view. It crashes when TABbing from layout, or when trying to pan and zoom in schematic. I’m using Chrome Version 78.0.3904.97 on Mac

I now have this problem on several older designs as well. Absolutely no response from support. I guess Upverter is a dead end?
