Disk Warrior - Mac OS Services Failure

I am having Repeated Mac OS Services Failure errors in DiskWarrior 5.0 trying to rebuild directory on an external drive

iMac (Retina 5K, 27-inch, Late 2015) using High Sierra

-------------

"DiskWarrior has successfully built a new directory for the disk named "KENZO01." The new directory cannot replace the original directory due to an OS X services failure.

Try rebuilding again. If this problem persists, please restart from a Recovery disk and then try rebuilding again."

------------------

Tried 3 times
