I have not had any crash issues with executing the profiler (scan my PC). I have watched it scan the HD, and while at times it looked like it was stuck (long paths get truncated when uber long, so it doesn’t appear to update).
I exported the safe list. made a tiny file… like ~130k
I selected a file and created a customer safe list without error.
I selected to edit my custom list, and found it to be empty.
