Hey there Davi,
If you are having account level issues I'd suggest getting in touch with Shopify Support directly, due to the sensitive nature of your account details.
There are many instances of this particular error, most often resolved through the Shopify Support system. Taking this route, a team member can look into your account directly and escalate your support ticket if necessary.
I've seen this query in quite a few threads, hope I could be of assistance!
