For anyone still having this problem, I tried every trick under the sun to fix this issue happening to me with this same exception_access_violation.
The solution ended up being very weird: apparently on Asus motherboards, there’s a sound controller called Sonic Studio that conflicts with Unreal. Go to Device Manager and look for a driver called Sonic Studio (or Sonic Studio Virtual Mixer) and disable it. Once I did, Unreal Engine stopped crashing.
