Whenever I go into Sleep mode the first time it will just reboot, then it will sleep the second time. Asus Dark Hero. None of my other Windows 10 machines have done this, pretty sure its an Asus Dark Hero problem.
Just a guess. Some device may need a driver update. I seem to recall many years ago similar behavior and it was driver related.
All drivers fully updated according to Asus site. It is also waking on lan when I activate my laptop, this bios [latest] doesn't even seem to have a wake on lan setting to disable 😕
