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.
