App Designer Error Message.

I randomly get the following error message in my app designer app.

1. How to I determine which line of code is causing the issue? The error does not occur when stepping through the code. Matlab does not provide a line number for the error/ warning.
2. How do fix the issue?

That's something broke in the internal TMW graphics code -- think you'll need to send this to official support to have any chance of any resolution.
