Error inside Try that does not trigger catch

I have a function that searches for a text in a PDF viewer using the "DevExpress.Xpf.PdfViewer.PdfViewerControl" control. The variable "MyTextSearchParameter" and "ViewerControl" is not null, but the first time I run the function an error always occurs -perhaps because the control is not ready (internal error)- but the catch is not triggered and the image is displayed. How can I make the catch trigger?

    DevExpress

    That's a 3rd party control, if you have an issue with, contact the software vendor support.

    I make the catch trigger?

    It do, but not in debug mode, when you have switch of the option exception handling, see

    https://learn.microsoft.com/en-us/visualstudio/debugger/managing-exceptions-with-the-debugger?view=vs-2022

    => The debugger is configured to break execution before any handler is invoked.
