What is the compatible version of kuberntes version in the cluster to upgrade Jenkins lts 2.426.3?

I just upgraded the Jenkins to LTS 2.426.3 successfully using Helm. Post upgrade I observed the kubernetes pods not able to provisioned to execute the jobs where as custom agents able to run fine. I just want to know if Kubernetes version is crucial to upgrade to Jenkins to latest as my Jenkins running on K8s cluster on AWS. The current version of Kubernetes is 1.21.
