BSOD nt!KeBuckCheckEx FAILURE_BUCKET_ID: AV_nt!KiDispatchException

[Flerov]

I've compiled the testlibelevate and passed it a handle to a driver. When trying to restrip handle rights I get BSOD.
Any ideas what went wrong ? What AV mech. could have caused this BSOD? Thanks a lot. I'm trying my best to learn but I'm still new to this

WinDbg gives me the following:
