Apple updated their release notes to instruct users to download Xcode from their developer website instead of using the Mac App Store version:
> If you’re using Swift packages either standalone or as dependencies in an Xcode project or workspace, the Mac App Store version of Xcode fails during package resolution with the error “Internal error: missingPackageDescriptionModule (86435800)
> Workaround: Download Xcode 13.2 directly from the Apple Developer website.

Looks like it's a bug in the incremental updater.
