How to investigate NDIS Test Protocol Drivers assertions

HLK failing NDISTest6.0 - Mini6Send triggering BSOD.
From stack it is obeserved that ndprot630 assertion is hitting.
what is the proper way to investigate ndprot630 assertion.
HLK verification driver threads not showing much information why this assertion is trigger in NDprot driver.
Tried to check pending OIDs, NBLS using !ndiskd.netadapter.

Stack:
nt!KiBreakpointTrap+0x311
NDProt630!CNDTKeLog::NDTKeDoAssertion+0xd2
NDProt630!CNDTSimpleSendCommMgr::SendAtPassive+0xbaNDProt630!CNDTCommunicationManager::WorkerThreadCallBackRoutine+0x67
nt!PspSystemThreadStartup+0x55
nt!KiStartSystemThread+0x28

Not familiar with this driver or these tests, but presumably there's an error message along with the assert?
