### What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 22

### Reproduction steps

1. Run this pipeline
```
#!/usr/bin/env groovy
pipeline {
agent none
environment {
CUSTOM_WS = "/home/jenkins/workspace/check${new Date().format('yyyyMMdd')}-${System.currentTimeMillis()}"
}
options {
buildDiscarder logRotator(numToKeepStr: '30')
}
stages {
stage('Check') {
agent {
node {
label "cc"
customWorkspace CUSTOM_WS
}
}
steps {
sh "printenv"

}
post {
cleanup {
cleanWs disableDeferredWipeout: true, notFailBuild: true, deleteDirs: true
}
}
}
}
}

```

The label is in my Cloud config templates.

### Expected Results

One slave is provisioned.

### Actual Results

Two slaves are provisioned for ~10 seconds, then one of them is used and the second one is destroyed.

### Anything else?

```
