Safari does not run after installing Monterey. Get message saying Safari quit unexpectedly. Any suggestions to get Safari back running>

To add - does this issue appear when booting into Safe Mode ?

Safe mode may help you resolve or isolate problems that you’re having with your Mac.

When you start up in safe mode, your Mac prevents some software, such as startup items, from loading, and it performs a check of your startup disk. Your Mac may take longer to start up because of the check.

First try launching Safari with the Shift key held down create a new, test library.  Import some photos and test to see if the same problem persists. Does it? This tells us if the problem is limited to your current library or is more wide spread.

Next, log into another/new basic admin user account, Set up users, guests, and groups on Mac,  and see if the problem persists. This tells us if the problem is limited to your user account or is system wide.

Suggest downloading the Application Etrecheck directly from a well Respected ASC Contributor.

The The Built in Security  is all that is required.

Try holding down the SHIFT key while you click the Safari dock icon. Hopefully that should allow Safari to start. Then go to Safari menu -> History -> Reopen All Windows from Last Session to get back to where you were. Unfortunately this must be done every time you restart Safari, at least until Apple fixes the Safari crashing bug.

This did not help on my Macbook pro 2019. Safari still crashes every time since updating to Monterey tonight, 12/8/21, even in safe mode.

Chrome works fortunately.
