Safari instantly crashes after Big Sur update

Hey there,

the moment I updated my macOS to Big Sur Beta, Safari crashes. I mean, immediately, no chance on clicking on preferences and figure something out.

The issue is different from other users here that have the same issue with Safari crashing after updating macOS.
  • removing Library/Preferences or /Caches doesn't help

  • installing Xcode 12 doesn't help

  • it has noting to do with the CoreSimulator offending alias

  • starting Safari from safe mode doesn't help either

  • starting Safari with no extensions via Terminal doesn't help

  • same issue for a new test account created on my Mac - crashes immediately

  • copying a link/clicking on a link results in an immediate crash as well

  • Safari does work however for a Guest account that is only able to browse the web

  • even reinstalling OS from macOS Recovery doesn't solve the issue

Honestly, I've tried everything I could think of. Kindly asking for help

In console I could see the Process: com.apple.SafariServices.ExtensionHelper [1030]
It's what is crashing Safari
Any possible solutions?

I'm running into the same issue. I used a terminal command to specifically turn off all extensions so I can't figure it out. Even an OS reinstall from Recovery did nothing!

I'm also getting a crash like this:

I have the same issue - I'm having to use Chrome as I cannot figure out how to get Safari to work again. Hoping that Beta 4 fixes this issue.
I have the same problem, switched over to FIREFOX but any help to Safari??????????????????
