  </code></pre>
  <p>This the the minikube start command I used:
  <code>minikube start --kubernetes-version=v1.19.15 --vm-driver=docker</code></p>
  <p>I have tried reinstalling minikube. It was working fine last week when I ran the same command.</p>
  <p>If more specific information is needed please let me know and I will edit the question. Does anyone know how I could go about fixing this?</p>
  <p>Thanks in advance.</p>
