After much searching I found that someone had previously installed dotTrace, then uninstalled it, however the uninstall wasn’t very clean and had left the registry littered with entries, though we’d removed some entries we thought could stop the problem there were more specific to that profiler.
After removing all registry entries related to dottrace and the CSID it presented we no longer have the error appearing in the event viewer.
See this answer for a script to aid in hunting down such entries: https://stackoverflow.com/a/36129656/361842
