Same!

I've been having the same issue for the past half hour, I think it's an error on Apple part.

Hi, sorry I forgot to write that. Yes I deleted it from the Copy Bundle Resources section.

I fixed it by going into the Build Phases of the Mac target and deleting the Share.appex from there!

Still no answer from the Feedback Assistant and the issue is still persistent.

Just to explain even further: the Private Records are always fetched, both in Xcode and in TestFlight/App Store, while the Shared Records, get only fetched in the Xcode version but never in Production (TestFlight/App Store). I've experienced this issue since they worked on iCloud with the new iOS15.
