Account ID email being discontinued in 45 days. Done steps in https://helpx.adobe.com/in/manage-account/using/create-update-adobe-id.html and https://adobe.ly/3VNIly5. "An error occurred with performing this action..." Error.

The problem is that all of my Adobe communication goes to the email address associated with my account and in a matter of weeks that email will no longer exist. When I log into my account and click on “Change Email” the error appears and I am unable to change the address.
