I had time to try again.
I do not have Riot Vanguard.
When I click on the desktop shortcut, I am asked to allow Hwinfo64 permission to change the system, then nothing.
System log entries:
Log Name: Application
Source: Application Error
Date: 5/14/2020 4:53:23 PM
Event...
No.
Nothing - not even a screen flicker.
Just the cursor implying an attempt to start the program - more like some kind of timeout.
I will examine all the logs more carefully to see if I can find something.

all stock/auto settings - no tweaks
ZERO load
hwinfo ran once on install, then would not run - even before reboot
immediate crash: win event 1000
Obviously - can't set debug mode in interface.
Reason to try hwinfo: see temperature...
