I have confirmed this bug as well.  Here is what I have done:

rsync failed when transferring large files over network with error 12
when using compression (z option).  rsync succeeded when I transferred
large files over USB to external SSD when using compression (z option).
rsync succeeded when transferring large files over network when NOT
using compression (z option).

Hope this offers some assistance in tracking and correcting this bug.

Title:
  error in rsync protocol data stream

Status in rsync package in Ubuntu:
  Confirmed

Bug description:
  When synchronizing to other systems, rsync exits with "error in rsync
  protocol data stream (code 12)".

  The problem occurs since ubuntu 22.04 LTS with two different
  destination systems not running ubuntu but plain debian. The error did
  not occur under 20.04 LTS.

  Synchronisation runs fine for most other files, but always stops at
  the same (relative large) file. The file itself has also been changed
  on a test basis to make sure the file is not the problem itself.
