MacOS X 10.15.7 Today I purchased a subscription to Sketchup Pro. I downloaded it and ran the installer. It seems to be be installed. When I double click to start, no windows appear, nor any menu bars. When I hit Cmd-Option-Escape to get to the Force Quit window, the app shows in the list as if it is running, but there is no user interface visible.
I followed the installation instructions carefully. I have also downloaded 2020 and 2019 versions, installed them, and have the same issue.
Any assistance would be appreciated.
