title: (WSL error at Startup) Press any key to continue
body: <p><strong>Problem:</strong></p>
  <p>When I launched Ubuntu 20.04, it pops up: &quot;Press any key to continue...&quot;, and then if I press any key, it exits immediately. This prevents me from using (typing any command) in Ubuntu WSL. (It occurred suddenly today. For the last couple of days it has been working properly.)</p>

  <p><strong>Attempts Tried:</strong></p>
  <ul>
  <li><p>LxssManager service is running. But LxssManagerUser and LxssManagerUser_60d78 are stopped. Manually starting the two services doesn't help as they automatically stop themselves right afterwards.</p>
  </li>
  <li><p>Hyper-V service is set to auto. Virtualization mode is enabled (task manager -&gt; performance -&gt; CPU)</p>
  </li>
  <li><p>Trying to <strong>re-run</strong> the update from here  <a href="https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel" rel="noreferrer">https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel</a>, but it shows WSL not installed (which is weird since I have been using it for a long time before)</p>
