I have the same issue after the update. It's not your pc.
You don't have to unplug, just hold down the power button to turn off the pc. Don't do it too many times though because this can corrupt your OS file system and you'll have to either repair or reinstall Windows.
BF6 has been very unstable for me. Good luck! Nothing in the latest update changelog mentions any bug or stability fixes. I'm just going to drop off this game till they address these issues.
Everytime it happened I would press the power button to turn it off but it wouldn't turn off, so I would be forced to unplug the power supply
