Matlab crash - Access Violation During VideoWriter Script

Thank you ahead of time for taking the time to read through this.

I am currently creating a Matlab program that manages multiple video objects. Specifically, it is a scheduling program for 16 cameras. It allows a user create recording schedules for the 16 cameras while synchronizing these recordings with another data acquisition device through the sending of network packets (managed by a different mex file). It also has features to review the video and data in synchrony, but that is beside the point.

The whole project is created in Matlab's GUIDE and has a fairly simple architecture. A user enters values into a table for scheduling the cameras, clicks on record, and a timer is created to manage the video file schedule. In the simplest recording scenario, I get an error. The user clicks record and a timer is created that is called every five minutes to 'split' the video files. It does this by calling a function that stops all of the video objects, closes the files, clears them from memory, creates new ones, and begins writing to new files. After this timer callback finishes executing, Matlab then usually attempts to call a privateGetVideoWriterLoggerFcn (for some reason) which attempts to point to the diskLogger property of a video input object. The problem is that this video input object was cleared in the timercallback, so this Matlab private function errors. This is strange and unexpected behavior for me. It is almost as if Matlab's invisible timer used for that function is queuing its calls instead of dropping them in the case of a busy response from Matlab.

Periodically, I get a Matlab crash just before Matlab attempts to call the privateGetVideoWriterLoggerFcn. The crash dump is below:

Thank you for your help.

I am not fully understanding the stack trace. As far as Tamutil.dll, the closest I have found is something like this: http://stackoverflow.com/questions/30711935/matlab-crash-during-acquisition-of-pointgrey-images, but I can't change my video input method. The overhead would be too much for Matlab/the PC/my sychronization to handle.

Can anybody help better interpret the stack trace or suggest any solution to this crash?
