safari is crashing now

Are you using any 3rd party optimizing software or anti-virus software? Hopefully not. If so, you should uninstall them as they have proven to cause more problems than they claim to improve.

Next, I would boot into safe mode to let the system run its diagnostics and fix things it finds wrong.

Just upgraded to 13.3.1 (a) (22E772610a) and Safari crashes
