The Kubelet service does not start after starting the MCP update in the EUS to EUS upgrade from OCP 4.10 to OCP 4.11

Issue

After unpausing the Machine Config Pool (MCP) in order to continue with the cluster upgrade, MCP starts the upgrade but the worker node is reported in NotReady, SchedulingDisabled state and when checking by ssh on the node, the kubelet service does not start.

$ oc get nodes |grep worker
