I confirm this as a HS issue and will investigate from here.

FATAL:  could not access status of transaction 21110784
which, in pg_subtrans, is the first xid on a new subtrans page. So we
have missed zeroing a page.

pg_control shows ... Latest checkpoint's oldestActiveXID:  21116666
which shows quite clearly that the pg_control file is later than it should be.

Chris, can you rearrange the backup so you copy the pg_control file as
the first act after the pg_start_backup?
