The first sleep works but the second sleep takes 3/4 reboot to boot the system in Sonoma

Hello!

I've successfully installed Sonoma.
When pc goes into first sleep everything works just fine, e.g., RGB light, MoBo goes off and wakes with a keyboard press perfectly.
But when it goes to sleep a second time, RGB light and Mobo keep running, and waking doesn't work at all with the keyboard or mouse. Have to do force shutdown and then it takes 3/4 reboots to boot the system.

Did USB Mapping properly with our own moderator @UtterDisbelief USB mapping guide

Any advice will be much appreciated.
Thanks and cheers!

I had same problems in my first EFI configuration of Z790 UD AX.
But now switched to MSI Z790 and changed completly my EFI settings.

The onlu suggestion that I can do: did you try disabling XMP?

Does XMP mean Memory profile in bios settings? please
