SketchUp Pro 2020 running slow

Can someone please help me understand why SketchUp pro-2020 is running slow? I installed the newest macOS update as well as pro-2020.

Every time I select a tool the spinning wheel comes up, spins about 5 seconds, stops, and then I have to reselect the tool only to start the process over. Not to mention my 3d connexion space navigator is basically pointless to use bc it will not work. I uninstalled and reinstalled 3d connexion software. Sketchup 2020 is a joke. What is the point of using a software that allows about 10 mins of uninterrupted work a day? This has been happening for the last three days. I cannot even use SketchUp. I’m thinking of switching to Rhino(ceros) and being done with sketchup.
