Same for me. I have now three irrepairable APFS disks lying around waiting for the engineers getting their act together. That is more trashed disks in 5 years of APFS than in the 25 years or so that HFS+ is around. HFS+ was always salvagable somehow if there was a problem. APFS? not so much. What a poor performance on Apple's part.

The correct team is still missing in my Xcode prefs. All the tricks above didn't help. Apple is fast asleep…
