title: Visual Studio crash on typing in VB.NET source code editor
body: <p>I'm facing a strange instant crash of Visual Studio when I type something in the VB.NET source code editor.</p>
  <p>C++ or C# source files still can be edited successfully. Also, some keys still work in the VB editor, for example <kbd>tab</kbd>, <kbd>return</kbd> or even copy and paste text via <kbd>CTRL</kbd>+<kbd>C</kbd> and <kbd>CTRL</kbd>+<kbd>V</kbd>.</p>
  <p>This problem literally came over the weekend as editing files in VB.NET projects worked well on Friday but failed right away on Monday. I haven't modified any settings or updated anything.</p>
  <p>I had a look at <a href="https://stackoverflow.com/q/38186837/1879699">similar</a> <a href="https://stackoverflow.com/q/4791519/1879699">questions</a> regarding this issue but none of them were able to solve my issue.</p>
  <p>The crash happens no matter what I try:</p>
  <ul>
  <li>disable extensions one by one</li>
  <li>start VS in safe mode</li>
  <li>start VS with logging enabled (absolutely nothing in the log)</li>
  <li>reboot the computer</li>
  <li>load settings from a colleague's installation</li>
  <li>load default settings</li>
  <li>create new empty VB project</li>
  <li>use the Repair option of the VS installer</li>
  </ul>
  <p>Environment information:</p>
  <ul>
  <li>Windows 10 Version 20H2 (OS Build 19042.985)</li>
  <li>Visual Studio Professional 2013 Version 12.0.21005.1 REL</li>
  <li>Visual Studio Professional 2017 Version 15.9.36</li>
  </ul>
  <p>Other installed software that might be relevant as it integrates into Visual Studio:</p>
  <ul>
  <li>IncrediBuild Version 9.5.0 (Build 3385)</li>
  <li>DevExpress 16.2</li>
  <li>DevExpress 20.1</li>
  <li>ReSharper 2020.2.4</li>
  </ul>
  <p>I doubt that an extension is the reason for the crash as the crash still occurs when extensions are disabled or VS is run in safemode. Right before one crash (in safemode) the following message was displayed:</p>
  <pre class="lang-none prettyprint-override"><code>Please wait for an editor command to finish...
  </code></pre>
  <p>Additionally, breakpoints can't be set anywhere in the (VB) code.</p>
  <p>Anybody knows how to fix this issue without doing a complete reinstall of Visual Studio?</p>
