Changed vendor uuid

I updated a new app and the vendor uuid changed. I didn't change the way I generate the vendor uuid, but I confirmed that the uuid value I received from the app store is output differently. Can you tell me why identifierForVendor changes when I distribute it?

XCode 15.0 (15A240d)

The value changes when the user deletes all of that vendor’s apps from the device and subsequently reinstalls one or more of them.
