2 Ways to Fix Google Chrome Not Opening on Mac

Hello. After the latest upgrade google chrome looks be opening then just closes out after showing a blank screen for a few seconds. Never been a problem before. I have done all of the above but not working plus gone back to older chrome versions and the beta version and under a different ID. Any other solutions you can think of? On Mac OSX 10.15.7 on a iMac 21.5″ late 2013.
