OR
kubectl apply -f https://github.com

How have you installed the cluster?
Have you installed all the prerequisites for the k8s cluster?

I am able to complete below steps -

  1. Adding all 3 IP addresses as Master , worker1 and worker2 in /etc/host file
    2.Disable swap
    3.Enable Kernel Modules and Configure Networking
    4.Install Container Runtime (Run on ALL Nodes)
  2. Add Docker’s official GPG key and repository to grab containerd
  3. Install Kubernetes Packages (Run on ALL Nodes)
    Add the Kubernetes package repository
  4. Initialize the Control Plane

and next step is to install Cluster Networking .

Are you using these links in the Calico guide?

If you could share the error screenshot or paste it in a code block using the </> button in the editor ribbon, it would help us assist you better.

Edit: You should use kubectl create instead of kubectl apply while installing Calico CRDs.

Try fetching the CRDs with wget or curl and then apply with kubectl create -f
