First thing to check is that failures are not happening because dynamic sleep adjustment is being too aggressive. Try using option --disable-dynamic-sleep, which will cause ddcutil to use the sleep timings in the DDC/CI spec. If that doesn't work, try --sleep-multiplier 2.0, which will cause ddcutil to use double the specified sleep timings.

Option ---stats provides aggregate reports on the errors encountered. In the case of DDC data errors (i.e. corrupt data in a DDC/CI reply packet), option --ddcdata will report the error.
