DateTimePicker causing VS lockup

In my datetimepicker.valuechanged event, I had some code that was not being processed. So I decided to place a breakpoint at the first line of code inside that event block to check it out. As soon as the event was triggered, Visual Studio completely locked up.

There was nothing special about that code inside the event, but just in-case, I commented it all out and just placed a variable declaration as a test. Same thing happened.

Any idea why this would be happening?
