title: Interrupted debug at loading symbol yielded to ntdll.pdb missing
body: <p>I was launching and stopping debug in visual studio really quick as I was testing something in a DLL entry point and at some point I clicked by error on &quot;cancel&quot; in the loading symbols window. Since then, when I launch debug, I keep having an access violation because of a &quot;ntdll.pdb&quot; missing.</p>
  <p>I tried to load the symbols from Microsoft servers, but it takes ages. I would simply like to return everything back to normal, as it was before my miss-click.</p>
