I've created an iOS app that works fine. I ticked the box in Xcode for Catalyst and its works fine on my machine, my wife's MacBook, and also a friends iMac. However, during the App Review process it got rejected as it crashed.

Is anyone good at crash reports please? It seems to crash on Thread 8 - Core Location. I've just shown that portion of the report but if you need it all just let me know (didn't want to just dump a load of text that all):

This crash is due to missing the appropriate usage description for macOS -- the keys you use for iOS don't apply. Please add NSLocationUsageDescription.

Thanks for pointing me to NSLocationUsageDescription. If it's missing from the plist you get crashes on Big Sur, but not always.
The validation procedures in AppStoreConnect do not check this, apparently, I just got crash reports from the review team.

Confirming that it's still the case for the latest macOS Monterey version as well. I've got similar crash reports from the App Review team, the application didn't crash on any of my MacBook machines though. The crash report always contained Thread #_ Crashed:: Dispatch queue: com.apple.CoreLocation.0x... description, which was almost identical to the above.

Changing the key name in the Info.plist file from iOS/iPadOS-only NSLocationWhenInUseUsageDescription to macOS-specific NSLocationUsageDescription has solved this.
