Can't get sampling to work on Windows #814

For the life of me I cannot figure out why sampling mode is not working for me. I compiled my application with Tracy, zoning / instrumentation modes work as expected, but sampling just does not show up. I am running the application with admin rights, yet all I see is:

Does it work with other ETW based sampling profilers like UIforETW or visuals studios CPU profiler? I've had issues before after installing vtune broke access to the cpu sampling functionality

It works fine with visual studio's CPU profiler, and also with Superluminal which is also sampling-based.
