VB Studio access issues - "Sign On Policy denies access"

Summary:

We need to modify Fusion pages to add DFFs. When we attempt to modify pages using Visual Builder, we are brought to a page that says "Sign On Policy denies access". We are able to access Visual Builder for the test environment, but not for the dev environment. I checked the Sign On Policies in OCI for both identity domains and they appear to be the same. I am not sure what else would prevent me from being able to access Visual Builder from the application and cannot find any documentation related to this.
