Unexpected exception when use getContext and sh together in the latest version of Jenkins

Using Jenkins Ask a question
1

The following code use to work properly until I upgrade the Jenkins to Jenkins 2.303.2.

import org.jenkinsci.plugins.workflow.graph.FlowNode

node() {
    stage('hello') {
        def flow = getContext(FlowNode.class)
        echo flow.id
        sh 'echo hello' // fail in this step, very strange!
    }
}

Here is the error

WARNING	o.j.p.w.cps.CpsThreadGroup#saveProgramIfPossible: program state save failed

It will work if I comment either the getContext or the sh line.
Since it used to work properly, I guess it may be a bug of Jenkins.

What are you doing this for? I doubt this is a supported feature

I use getContext to get the id of the current stage, so that I can build a link to access the log to the stage instead of the whole job. It is a formal step with document.
Pipeline: Basic Steps (jenkins.io)
I have used this for a long time and it works well on Jenkins 2.235.2
But it just broken after we upgrade to Jenkins 2.303.2

You overlooked:
For use from trusted code, such as global libraries, which can manipulate internal Jenkins APIs.
So put in a function marked as @NonCPS could work, I guess.

import org.jenkinsci.plugins.workflow.graph.FlowNode

@NonCPS
def getFlowID() {
    def flow = getContext(FlowNode.class)
        echo flow.id
}

node() {
    stage("1") {
        getFlowID()
        sh "echo OK"
        
    }
}
