We're facing the same issue as reported in below post.
Using HLK 18362, re-installed OS/HLK software on client, same crash.
No issue when running RS5.
Is this a bug in the 19H1 HLK test kit?
A crash with exception code 0x80000003 occurred in module "vrfcore.dll" in
WexTraceInfo ThreadId=5852 ProcessId=4884 TimeStamp=1074741179 LogSessionId=0
[HRESULT 0x800706BE] A failure occurred while running a test operation:
(A crash with exception code 0x80000003 occurred in module "vrfcore.dll" in the
process hosting the test code while invoking a test operation.)
Try to delect vrfcore.dll on the registry entry for your application and try to
run, still fail
