ASRock x870 Phantom Riptiode wifi - Rebooting doesn't work

[Acastus]

Ok, so if I shutdown the PC and then start it up again it boots fine. If I try to just reboot normally, whether it's via windows or an application update, the entire system fails to boot to windows. All the fans are on as it would be in a normal boot but just no display. Any hints or ideas that could be causing this.

So far the Mobo is good except for this one issue.

Does it do it without xmp/expo disabled?

Does this give any clues:

The vid shows what happens to the lights when I reboot. After the white light comes on and goes off though the system just stays on with no output to the display.

I've tried with xmp off and it's the same scenario.
