MS Defender kernel driver install BSOD

[AsciiRobot]

I have recently had trouble bluescreening after windows updates running, and swapped my ram because I thought it could be that.

With new ram installed, I found something that might be relevant if someone could help me out:

 

Here was part of the minidump in windbg !analyze:
 

SYMBOL_NAME:  nt!RtlSidHashInitialize+57

MODULE_NAME: nt

IMAGE_NAME:  ntkrnlmp.exe

 

In event viewer, before the crash I had a defender kernel driver installed right before:

Service Name:  MpKslf9cb2f6a
Service File Name:  C:\ProgramData\Microsoft\Windows Defender\Definition Updates{9C2AE92D-6003-40A8-9D4A-AC280A03D884}\MpKslDrv.sys
Service Type:  kernel mode driver

 

Could these be related? both seem to have something to do with the kernel. And before swapping ram I wasn't even getting BSOD dumps just hard restarts.
