Visio add-in crashes, Faulting module name: ntdll.dll - crash

Question

I have created Visio (VSTO) Com Add-in.
After one of my users installed Visio 2016, Visio with the following error:
"Visio is running into problems with the '[add in name]' add-in.
If this keeps happening, disable this add-in and check the available updates.
Do you want to disable it now?"
I not sure it's got to do with Visio 2016 only, but we've tried reinstall both 32/64 bit
(on Windows 10 64 bit operating system)

Here's what I've seen in the "Event Viewer"

I've done deep debugging and the location is random,
but I have noticed that in many cases the crash is at "save" location:
this.Application.ActiveDocument.Save();
I've done lots of web research and so far didn't find meaningful information.
Can anyone help on this?

Maybe out of your scope but I had same error without Visio add-in or whatever
Fix this by going to File - Options - Advanced in Visio, and checking out the "Disable Enhanced Metafile optimization" box to disable this option, under Display

worked fine for me
