[ORGANIZATION_DISABLED] Organization is locked

All I want to do is build a small customer account extension. I don’t have a partner account or organization, I only work on a single store. I have developer permissions for that store. When using the Shopify CLI to scaffold an extension I get this error:

The BusinessPlatform GraphQL API responded unsuccessfully with the HTTP │
│ status 403 and errors: │
│ │
│ “[ORGANIZATION_DISABLED] Organization is locked.”

I have logged out and logged back in to my one account. I get the same error if do shopify app dev --store [mydevstore].myshopify.com

Can anyone help?
