Xcode 12 beta 4 crashing on launch, Intel Big Sur beta 3

I just downloaded Xcode 12 beta 4 and it crashes every time on launch for me on my Intel iMac. I tried deleting my prefs, derived data, and ~/Library/Developer/Xcode/UserData, as well as running from a separate user account, and it crashes every time with the below stack trace. The same version of Xcode launches fine on my DTK. Anyone else seeing this?



I updated to Big Sur beta 4, and I still get this crash. I've filed it with Apple as feedback FB8264823
I am having a lot of issues with Xcode vanishing, it is not even reporting a crash, just disappears. Not doing anything complex, just small projects with basic Swift & SwiftUI. It has only started happening with Beta 4, had no issues previously.
  • Xcode Version 12.0 beta 4 (12A8179i)

  • macOS Big Sur 11.0 Beta 4 (20A5343i)
