Hi Dhruv,
It seems like your APIM instance is stuck in the "Updating" state because the service is transitioning, and the "ServiceLocked" error is blocking further updates. This typically happens when there’s an issue during the APIM update process, often related to changes like adding custom domains or certificates.
Sometimes APIM can take a while to fully apply changes. If possible, wait a bit and retry the request.
Please check these threads for more details on these issues :

This occurs because the previous operation was still in progress. Could you please retry and confirm if you were able to purge the service successfully now?
I hope this addresses your query. Please let me know if you need any further assistance or clarification.
