Upgraded k8 worker node from ubuntu 20.04 to 22.04. DNS resolution/networking inside pods doesn’t work & pods keep crashing/restarting

I have a k8 cluster based on Ubuntu 20.04 1 master and 3 worker nodes. I drained one of the worker node. Put kubectl,iptables, kubeadm, kubelet & containerd packages on hold. OS upgrade to 22.04, went smooth, but after upgrade pods (kube-system daemon-sets) kept crashing. One of the issue I found is that DNS resolution is not working inside pods residing on upgraded node. When I revert back to ubuntu 20.04 everything works fine. Anyone help/suggestion please
