Safari won't open. It crashed when I tried to open it and now I get the following message when I try to open it: Then when I click reopen I get the following message:
If I click reopen it starts the sequence over again. I rebooted my laptop and the same thing still happens.

Another thing you can try is to press the shift key while clicking Safari to open it. This forces Safari to ignore the previous windows.
The error message seems to be related to the bookmarks. If you synchronize Safari with iCloud, try to turn it off to do some tests. (Go to System Settings > [your name] > iCloud and turn Safari off.) If Safari operates normally, turn the synchronization back on.

Am I to understand the Safari app fails to launch, or it launches with no open windows or tabs?
The distinction is important. Obviously you want the latter, after which you should be able to load a new web page such as https://www.apple.com/ that will not cause Safari to crash.
Another troubleshooting step would be to boot Safe Mode, and launch Safari while in that mode: Start up your Mac in safe mode - Apple Support.
Then, reboot normally and test again.
Does it crash if you click Don't Reopen?
That choice will not reopen Safari's previously opened windows or tabs, which may have caused it to crash.
If I click Don't Reopen it doesn't reopen. It crashes and shows the second error message.
Neither holding the shift key or turning off iCloud changed the behavior. I tried tuning iCloud back on again and it still crashes as described.
It fails to launch - it briefly shows a new safari window but then that disappears and I get the repeating error messages.
I'll try safe mode tomorrow & let you know what happens.
Last night's OS update corrected this problem
Great! Thanks for the update.
