Hi @apoorvaagar,

This looks like a Service Operations Workspace configuration issue after the Australia upgrade. ServiceNow has documented cases (KBA1756084,  KB2817603) where UI actions disappear when the workspace/UI Builder records are not properly updated, so I would check the workspace plugin versions and verify that the Retire/Create Feedback/Edit actions still have the correct sys_ux_form_action, sys_ux_form_action_layout_item, and sys_ux_m2m_action_layout_item link.

Hope this helps!
