An earlier report on standby issues seems to remain with a GeForce card suggesting the video card is not the problem. The settings of 5 minutes for the LCD and 10 minutes for standby are not honored. Changing standby to 15 minutes seems to work suggesting the DMI, UEFI and Windows are still not interacting properly.
Recent BIOS updates have not resolved this defect for the MSI X570-A PRO motherboard. So much for the EPA Energy Star program.
A defect in the Steam loader also fails occasionally forcing authentication when awakening from standby.
