SYSTEM_THREAD_EXCEPTION_NOT_HANDLED exception found when starting driver service

NTSTATUS DriverEntry (_In_ PDRIVER_OBJECT DriverObject,_In_ PUNICODE_STRING RegistryPath){ NTSTATUS status;

UNREFERENCED_PARAMETER( RegistryPath );

PT_DBG_PRINT( PTDBG_TRACE_ROUTINES,
              ("FsFilter1!DriverEntry: Entered\n") );
status = FltRegisterFilter( DriverObject,
                            &FilterRegistration,
                            &gFilterHandle );

FLT_ASSERT( NT_SUCCESS( status ) );

if (NT_SUCCESS( status )) {

    //
    //  Start filtering i/o
    //

    status = FltStartFiltering( gFilterHandle );

    if (!NT_SUCCESS( status )) {

        FltUnregisterFilter( gFilterHandle );
    }
}

return status;

}

this code is showing me an error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED and the system is being switch off when I am trying to start service after installation
