Xcode keeps crash after upgrade to macOS 26

It would be helpful to have this as a bug report with that crash report attached. Please post the FB number of your report here.

After that, I would first try to just reinstall a freshly downloaded copy of Xcode 26 from either the Mac App Store or from the Apple Developer website. If it continues to crash after doing so, try running xcodebuild -runFirstLaunch. Let me know the results to that point here.

I don't know why I can't comment on the reply, so I have to make a new reply.

• Reinstall from App Store keeps failing during the downloading phase.

• Reinstall by manually downloading from developer website will get the same crash.

• Run xcodebuild -runFirstLaunch has no effect.

i have the same issue too, xcode safari unable to launch, when open will report error :
