title: Could not find Unity Package Manager local server application at [d:/games/Unity/Editor/Data/Resources/PackageManager/Server/UnityPackageManager.exe]
body: <p>When I start the Unity3D 2020.2.1f1 then this window pops up:</p>
  <pre><code>Could not find Unity Package Manager local server application at 
  [d:/games/Unity/Editor/Data/Resources/PackageManager/Server/UnityPackageManager.exe]
  Missing files could be the result of an antivirus action or a corrupt Unity installation.
  </code></pre>

  <p>The mentioned file doesn't exist. The trick is that I reinstalled everything, copied this file in advance and realized that when you start it is got deleted. How can this be solved?</p>
  <p>So far I tried the following:</p>
  <ul>
  <li>Reinstalled the Unity and hub</li>
  <li>Cleaned the registry through CCleaner</li>
  <li>The firewall is disabled, and the incoming/outgoing rules for unity.exe file are enabled</li>
  <li>There is no antivirus in the system</li>
  <li>I set the environment variables in Windows</li>
  </ul>
  <p>I tried a bunch of solutions that I could find, but nothing helps. Can anyone help me with this? Thanks in advance for any help.</p>
