Try using the simultaneousGesture modifier instead of gesture. https://developer.apple.com/documentation/swiftui/view/simultaneousgesture(_:including:)

This seems to have been resolved now for me!

@DTS Engineer Thank you for the hints. I was building with Xcode 26 Beta 3 and running on macOS 26 Beta 5 (not 4 as stated in my original message). I updated to Xcode 26 Beta 5 and it no longer crashes!
