WPF Print visual ntdll.dll crash

Having a strange crash on some machines using when printing via an application (WPF Windows desktop app, Win X64, Core 3.0)

I need to print a usercontrol silently (no print dialog popup) from a specified printer (currently just the printer name stored as text) I'm using the below code to do so.

var server = new PrintServer();
var queues = server.GetPrintQueues(new[] { EnumeratedPrintQueueTypes.Local });
if (queues.Any(Q => Q.FullName == ThePrinterName))
{
    printDlg.PrintQueue = queues.Where(Q => Q.FullName == StaticData.PrinterName).First();
}
printDlg.PrintVisual(TheUserControl, PrintTitle);

However on some machines (I cant reproduce it) it causes a hard application crash below the level that WPF allows capturer / logging on.

Only logs of the error I can find are in event viewer like the below which I believe point to a heap corruption which "should" be mostly impossible in managed C# code so must be something else printing wise. I think it must be something relating to print visual/the print dialogue setup as printing via other methods (like printing an image) work fine.

Any pointers would be greatly appreciated!

    Exception code 0xc0000374 means you're facing heap corruption.

    The most common causes for this kind of error are these two:

    1. A faulty RAM module
    2. Buffer overrun, when one thread tries to read something and another thread has removed data in the meanwhile. This shouldn't happen in managed code as far as I can tell.

    You probably have to get Windows Debugging Tools to figure out what's wrong if you can't debug the application in the dev environment.

    Hi narrowed the issue down to explicitly Zebra label printers. So likely some issue between the WPF XPS printing method and the Zebra driver. I've contacted zebra for support and will update here should I recieve any relevent information.
