Outlook crashed with my IM provider enabled on 2013 or above

I've implemented the Outlook IM provider according to the official guide: https://docs.microsoft.com/en-us/office/client-developer/shared/integrating-im-applications-with-office

And host it via the COM server published at: https://code.msdn.microsoft.com/windowsapps/CSExeCOMServer-3b1c1054

Everything works fine. Except for: If I manually close the COM Server, or I put PC to sleep state, then wake up again. It will make the Outlook crashed.

From the event viewer, it only shows:

Faulting application name: OUTLOOK.EXE, version: 16.0.10730.20264, time stamp: 0x5c2577a8
Faulting module name: ntdll.dll, version: 10.0.17763.194, time stamp: 0xe8b54827

Report Id: 7cb2212f-d173-4928-b5bf-6cdef15fc90c
Faulting package full name:

Does anyone know how to fix it? It would be greatly appreciated.

We tried adding log-tracker in each point that Outlook may connect to in my IM provider app, but without any change to catch the detailed information when Outlook crashed.

UPDATE: 2019.1.29

NOTE this exception only happens on Outlook version >= 2013, it works well in Outlook 2010...
