Hello Hector,
Thanks for reaching out to us, if you created this subscription yourself, you should have the owner role when you check on subscription.
But according to the screenshot you shared in the comment, it seems you should be under a subscription called DST-MSVD-Production. Is this subscription you created?
If yes, please contact Azure Support team - https://azure.microsoft.com/en-us/support/create-ticket/
You can ask support team to check on your subscription status and fix the current assignment issue. If you just created your subscription, this error may be go away naturally after 24 hours.
I hope this helps.
Regards,
Yutong
