Clicking play causes 100% system Interrupts

Hello fellow heroes,
I have an issue where when i click play on battle.net my entire pc comes to a crashing halt. I can see in the task manager that my cpu gets pinned at 100% by system interrupts. It was possible for me to kill battle net in the task manager which returns my pc to its normal state. This happens every time even after a lot of trouble shooting.
I have tried so many things. I have reinstalled the game on multiple drives. I have reinstalled the battle net launcher on multiple drives. I reinstalled my gpu drivers and chipset drivers. Removed my OC on my CPU. Other games run perfectly fine. OW2 ran too a few days ago. I have absolutley no idea as to whats going on.
Idk if it helps but here are my specs
13600k
Rtx 3080
32 Gigs of ram
Ow2 installed on a (half full) fully working ssd
Thanks in advance for any help in this ^^

Does it happen if you open the game without directly without the launcher? Does it happen on other titles like WoW?

If i launch the game without the launcher it just opens the launcher. It happens with no other game. However ow is the only game i have on battle.net. But every other game from cyberpunk to Civ 5 works perfectly.
Edit:
I tried to open the game without the launcher by using the exe in the _retail folder and the same thing happend. So it happens either by using the file or clicking play in battle.net
