Failed to run kubelet" err="failed to run Kubelet: unable to load bootstr

Cluster information:

Kubernetes version:1.21.5

Hi Team,

I am getting below error in kubernetes cluster:

“failed to run kubelet err= failed to run kubelet unable to load bootstrap kubeconfig”

Due to it I am not able to start kubelet service on one of worker node in cluster.
I have already renewed the certificates using

kubectl certs renew all

But still I am facing this error.

Please help me in this issue.
