title: Azure Devops specified logon session does not exist
body: <p>We use Azure Devops for our git repository and we previously had an issue every so often where we would get a &quot;Terminal Prompts disabled&quot; error. When we upgraded to Visual Studio (2019) version 16.8.1, this went away and all seemed fine. However, after about 2 weeks on this version I and some of our other developers are now getting this error:</p>
  <pre><code>Failed to push to the remote repository. See the Output window for more details.
  Updating 7df912b..b4954c1
  Git failed with a fatal error.
  Failed to write item to store. [0x520]
  A specified logon session does not exist. It may already have been terminated
  POST git-upload-pack (909 bytes)
  remote: Azure Repos        
  remote:

  </code></pre>
  <p>Sometimes it will also say that it failed and to check the Output window. When I go to check the error, it will say &quot;check the output window&quot; in the output window itself with no further error message. I have tried clearing my git credential tenant.cache file and IdentityService folders in AppData, but have had no luck. The most odd thing though is that all of the pushes and pulls seem to still work. Has anyone experienced either of these errors?</p>
