Not nearly as disruptive as what you're experiencing, but I do have the same symptoms (Windows 10.0.18362).

Have you found a way to eliminate it? If not:

In the Windows Task Manager, "avidappmanhelper.exe" executes and stops every few seconds, and often reports trillions of page faults.

I haven't found a way to stop or disable it though -- and it does not appear to be required by the ProTools exec.

Something to check out if you / future searchers are stuck.
