Spotlight has quit unexpectedly
The path shown in the crash log is within Xcode, specifically the iPhoneOS.platform iOS.simruntime. This Spotlight is the one running in the simulator, not the one in macOS. This is not a ‘real’ issue and can safely be ignored unless you’re testing Spotlight functionality within the app you’re running in the simulator.

Disabling Allow Spotlight Suggestions in Look Up on the simulator Settings app
Adding CoreSimulator to Spotlight privacy
