A regression has been identified in the Assisted Installer OVE UI for versions 4.21 and 4.22 in disconnected environments. Upon initial launch or page refresh, the UI intermittently displays a blank page containing only a spinning wheel and the text "Technology Preview."During this state, the expected cluster detail forms and configuration fields are completely missing. The issue is transient, typically lasting a fraction of a second to a few seconds, but often fails to transition to the actual application state, causing failures in automated testing. This behavior was not present in version 4.20.z.  

    4.22.z, 4.21.z

    Intermittent (High Frequency)

1. Launch the Disconnected Assisted Installer OVE UI (v4.21 or v4.22).
2. Observe the initial page load OR perform a standard page refresh (F5).
3. Alternative for Automation: Boot up a node with the OVE ISO and Execute the Golang-based UI automation script to navigate to the cluster details page.

4. Alternatively, kick of a CI job e2e-agent-compact-ipv4-iso-no-registry against 4.21 or master branch of https://github.com/openshift-assisted/assisted-installer-ui and monitor the results in a live CI environment

    The UI displays a blank screen with a spinning loader and "Technology Preview" message for a brief period.The usual cluster configuration forms are delayed or fail to render entirely, causing automation scripts to timeout or fail due to missing elements.

  The UI should load the cluster details form immediately without a transient blank "Technology Preview" state.Consistency with 4.20.z behavior, where the form elements are available upon the completion of the initial loading sequence without an intermediate empty state.  

Frequency: Occurs "very often" on refresh and frequently on initial launch.

Automation Impact: The Golang-based UI automation is consistently affected, as it expects the form elements to be present in the DOM for interaction.

Comparison: Version 4.20.z is stable and does not exhibit this flickering/blank state.
