Hello
Do you happen to be the Global Admin of the tenant where the Azure subscription is located? If you are, or can get a hold of a person who is, you/that person can use Global Admin to gain access to all subscriptions within your tenant.
To do this, log in as the Global Admin account and go to Entra ID
In the left pane select "properties", then under "Access management for Azure resources" there is an option to let the current Global admin account manage all Azure subscriptions in this tenant :)
Hope this is helpful and remember shared knowledge is the best knowledge 😊
Best Regards,
Timmy Malmgren
