Crashing when fighting with 2h sword

Game mode: [Online
Problem: [Crash | Bug | Performance | Misc]
Region: America

I have had a crash twice now fighting NPC enemies, both times different factions. Both times i have noticed where when i used the final heavy attack combo delivering a killing blow to the NPC. My screen goes black and i hear a loud annoying noise from the speakers. I cant exit the game or do anything on my PC unless i completely restart it. It does not happen every time, but it has happened twice within 2 days

Steps on how to reproduce issue:

  1. 2h sword
  2. Heavy attack NPC
  3. Deliver killing blow with the last heavy attack
