Installer presubmit job pull-ci-openshift-installer-main-azure-ovn-marketplace-images has been failed at step of post check since Feb 14th.

osImage is specified as below in install-config.yaml for this job:
=====================
controlPlane:
  architecture: amd64
  name: master
  replicas: 3
  platform:
    azure:
      type: null
      osImage:
        publisher: azureopenshift
        offer: aro4
        sku: aro_417
        version: 417.94.20240701
        plan: NoPurchasePlan
compute:
- architecture: amd64
  name: worker
  replicas: 3
  platform:
    azure:
      type: Standard_D4s_v3
      osImage:
        publisher: azureopenshift
        offer: aro4
        sku: aro_417
        version: 417.94.20240701
        plan: NoPurchasePlan

After installation is completed, we checked whether both cpms and worker machineset had expected image settings, and the step failed because that osImage in worker machineset was auto-updated to aro_420 image.
=====================
image setting in machineset ci-op-dnxzbtqs-ebf52-xtbs8-worker-centralus1:
{
  "offer": "aro4",
  "publisher": "azureopenshift",
  "resourceID": "",
  "sku": "aro_420",
  "type": "MarketplaceNoPlan",
  "version": "9.6.20251015"
}

Looks like that this was updated by MCO, found below information in machine-config-controller logs.

    4.22 nightly build

    Always

    1. Specify osImage in install-config with ARO NoPurchasePlan image
    2. Install cluster
    3. Check worker machineset to ensure that image is consistent with osImage defined in install-config.yaml     

    Image in worker machineset spec is auto-updated to latest one

    Image in worker machineset spec is the same as osImage defined in install-config.yaml
