How to trace an unhandled exception in C++ using Visual Studio 2017

I am currently working on fixing a project for a client. A little information about the project first:

1. Originally developed in Visual Studio 2012 using xp_v110 build tools
2. Multiple projects in the solution
3. Currently updating/debugging in Visual Studio 2017 using VS 2015/xp_v140 build tools
4. Working on Windows 10

The application will run in debug mode, however if I just leave the application after starting the debug session (i.e. not opening/clicking on the application to open it as it starts minimized in the tray), the application crashes after 1-2 minutes.

Unfortunately the IDE is showing that the crash is taking place in chkstk.asm with the following message:

Exception thrown at 0x0064EDF9 in <<exe name>>: 0xC00000FD: Stack overflow (parameters 0x00000000, 0x000A2000).

I have updated the exception settings to break when all C++ Exceptions are thrown, checked the box that says "Break when this exception type is thrown", and wrapped the initial method that runs in a try block, however I can never catch the error in the C++ code; it always occurs in the chkstk.asm file.

Any suggestions on how I can find out where in the C++ code the exception is occurring. Like I said, this is an update for a client and the original programmer is not available, and they never commented their code, so it is difficult enough trying to go through all this. Any help/suggestions would be greatly appreciated. Thanks in advance.
