Artboard keeps panning to the right and touch the zoom tool makes it zoom in to a huge size

Hi I have attached a video showing that when my pointer or any tool on the artboard it slowly pans to the right. I cannot get it to stop. Also when I pick up the zoom in/out tool it zooms in a cazy amount and I can't get it back to a normal view without using the "VIEW" drop down window. The zoom in/ out tool goes crazy and doesn't function properly at all. I can draw and place type and use all the tools but the artboard keeps waking to the right while use the tools.

 I unplugged all printers and restarted and only have the lastest update of illsutrator running with no other programs running - this was no help.

 I am using an Imac14,1 Quad intel Core i5 Running Catalina 10.15.7 8 gb 1600 MHZ DDR3 I am not anwhere near using up the memory.
