(Solution) Power button become shutdown since Windows Insider Build 14942 (Also affect the other build 14951, 14955 and 14959)

The problem is caused by the "power setting - When I press the power button" change to "Shutdown". (I hit this issue on my Chuwi Vi8 Plus tablet)

 

The solution is change the "power setting - When I press the power button" to "Sleep"
