I had some strange behavior with the two instances of visual studio I had open. The one I had attached to the Monitor went into break mode as soon as I selected “Start Graphics Debugging” in the other, and that one didn’t respond until I clicked “continue” in the first. However, after clicking “continue”, I got the usual messages and nsight crashed. The instance of Visual Studio which had been attached to Nsight was now unattached.
I’m not sure where the dump file would be located, and I don’t know how to access the callstack after the monitor crashes, as the callstack window in visual studio disappears.
However, there are contents in the “output” window which look like they might be useful: https://pastebin.com/pqfd3rTP
In particular the lines
An unhandled exception of type 'System.NullReferenceException' occurred in Nvda.Messaging.Interop.dll
Object reference not set to an instance of an object.
Let me know if those are of use, or how I can find the dump file / record the callstack.
P.S. I may not be setting up the tutorial entirely correctly for nsight, come to think of it, as it’s hard to confirm when I get the same error regardless of what I do. However starting debugging normally through V.S. does correctly load the window with a properly rendered triangle, and is, as far as I can tell, working correctly.
