Body: <p><strong>The issue:</strong>
  For any vagrant box, whenever I run the vagrant up command, I get the following error:

  <p><strong>What I have tried:</strong></p>
  <ul>
  <li>Tried having VirtualBox window open while running vagrant up command</li>
  <li>Installing the latest VC Redist for my AMD64 (x64) and Also tried (x86) VC Redist.</li>
  <li>Followed instructions in the following video, as a previous video of this channel resolved my CentOS 9 issue: <a href="https://www.youtube.com/watch?v=2FeqyzY4Y14" rel="nofollow noreferrer">https://www.youtube.com/watch?v=2FeqyzY4Y14</a></li>
