I had to Uninstall Box using CleanMyMac
I then had to reload a clean system (High Sierra)
There still seemed to be some broken threads for box in the Cache folder that I found using CleanMyMac again after the clean install
Once these were removed I reinstalled the Box drive without any incidence
I had deleted the Cache folder and uninstall box before this procedure without success
It seems that reloading a clean system folder made all the difference in my attempt to overcome this obstacle
