Hello all,
I may have some good news for you.
I have discovered why my RYZEN MASTER has been failing, and it is a conflict with NZXT CAM. Just exit CAM from the System Tray, then launch RYZEN MASTER with no trouble.
FYI, I have discovered a similar conflict between HWiFO and ThermalTake TT RGB Plus. Exiting RGB Plus allows HWiFO to run as well.
