PC won't go into sleep regularly and wake up in an hour after upgrade to OS Build 19041.388

Hi,


Windows 10 Pro, 64 bit. Recently upgraded to OS Build 19041.388


Since the upgrade, I have noticed that the PC no longer enters sleep mode as regularly as before the upgrade.


Before the upgrade, PC will enter sleep if idling for 30 min. I have noticed it will wake up around midnight by itself but will go back to sleep after a few min.


After the upgrade, I have not seen it once entering sleep mode after idling. If I make it sleep manually, it will wake up in less than one hour. Once awake, it won't go back to sleep.


How could I troubleshoot? Some information below


In the Event Viewer, the most recent wakeup is 0:36.
