title: XLWings Throwing Error on quit after a copy
body: <p>When running xlwings 0.26.1 (latest for Anaconda 3.83) or 0.10.0 (using for compatibility reasons) with the latest version of <code>Office 365 Excel</code>, I get an error after moving a sheet when running <code>app.quit()</code>:</p>
  <pre><code>import xlwings as xw
  import pythoncom
  
  pythoncom.CoInitialize()
  app = xw.apps.add()
  app.display_alerts = False
  app.screen_updating = False
  
  wbSource = app.books.open('pathSourceTemp')
  wsSource = wbSource.sheets['sourceSheet']
  wbDestination = app.books.open('pathDestinationTemp')
  wsDestination = None
  
  #Grabs first sheet in destination
  wsDestination = wbDestination.sheets[0]
  
  
  #Copy sheet &quot;before&quot; destination sheet (which should be 1 sheet after the destination sheet)
  wsSource.api.Copy(Before=wsDestination.api)
  wbDestination.save()
  
  #Close workbooks and app
  wbDestination.close()
  wbSource.close()
  app.screen_updating = True
  app.quit()
  </code></pre>
  <p>The final line causes Excel to throw an error that I have to click out of for the process to continue.</p>
