title: Visual studio error list shows empty results list
body: <p>After fixing errors and rebuilding the error list window still has empty placeholders and a count of zero errors.</p>
  
  <p><img src="https://i.stack.imgur.com/drvVY.jpg" alt="VS error list window"></p>
  
  <p>This only goes away after restarting VS</p>
  
  <p>It seems random, some days I dont get the problem at all with the same solution</p>
  
  <p>Trying to open one of the empty errors by clicking on it gives me a "Visual studio has encountered an unexpected error." message. </p>
  
  <p>Its driving me crazy. Cant find any help out there or other people reporting the same problem</p>
