I upgraded to 91.1.2 today and have been unable to open the program since. The program opens and I am asked to sign into Google for calendar sync but this window does not respond. Also the Preferences Tab is open which is not normal. The program hangs for about seven or eight minutes not responding and then crashes. The Crash ID is bp-96fabaaa-e5b9-4f12-841c-8a66e0210929 The program is using around 2.5 Gb of memory I have tried uninstall and reinstall but no success. I would like to go back to the old version but don't know how.
