panic: runtime error: invalid memory address or nil pointer dereference when use kubeadm

[bvivi57]

Describe the bug

When I try to do the "kubeadm init" command to initialize the first node of a kubernetes cluster, I get the following error.

[kubelet-start] Writing kubelet environment file with flags to file "/var/lib/kubelet/kubeadm-flags.env" panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x74d0aa]

goroutine 1 [running]: k8s.io/kubernetes/vendor/github.com/modern-go/reflect2.(*frozenConfig).Type2(0x189ee20, {0x1db32d0, 0x17f4dc0})

Reproduction steps

1. install kubeadm with tdnf install kubernetes-kubeadm
2. run "kubeadm init"

Expected behavior

The kubeadm command should finish and my cluster should be initialized.

Additional context
