Question Wake on Lan makes PC restart after shutdown ?

[EpselonZero]

Hi,
When I try to shutdown my pc using windows 10 shutdown button the computer just shuts down then restarts itself ?
I figured it out that if I turn off wake on lan in the bios it fixes the problem. However, I would like to know why wake on lan causes this issue ?
I have a gigabyte aorus b450 elite
ryzen 7 2700x
corsair hx 750
The bios is up to date as well as windows.

Even with wake on lan disabled I can't "update and shutdown", the pc just reboot.

I'm still dealing with this issue if anyone know what happen.
