In the past 2 weeks my pc immediately wakes up when i put it to hibernation, but only once, if i do it a second time right after it works just fine.

There is no logged event other then some kernel events for the immediate wake up. Only when it has successfully gone to hibernation the second time and i wake it using mouse or keybord do i get a power-troubleshooter event with the typical unknown wake source.

Its a self built mid-tower i built in 2019, and it was formatted about 4 months ago.

I had a very similar same issue and managed to fix with the following procedure.

In the settings of your computer network card, switch to "power management" tab, and check that, if the 2nd setting ("allow this device to wake the computer") is set, the 3rd ("Only allow a magic packet to wake the computer") is also set :

If the culprit is not hardware-related, you can check:

  1. if your computer may have "scheduled maintenance" active . In Control Panel\All Control Panel Items\Security and Maintenance\Automatic Maintenance, uncheck the box before "Allow scheduled maintenance to wake up my computer at the scheduled time". The related registry keys are:
; To change the policy, use the following key
;[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Task Scheduler\Maintenance]
;"WakeUp"=dword:00000000

; To change the user-specific settings, use the following key
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\Maintenance]
"WakeUp"=dword:00000000
  1. if some events that can way your computer are allowed (in the Power Plan, the Advance Settings of you active Power Plan has a Sleep/Allow wake timers setting). Use powercfg /waketimers to have the list of currently active timers. You can check Conclusively stop wake timers from waking Windows 10 desktop for details.
