Hi,
This seems to be an issue with your Restricted Caller access privileges. See an example below.
If you got to the table sys_restricted_caller_access, you will probably see that some accesses are invalidated or requested. If you change those again back to allowed, it should work again.
But note that you may need to change scopes to allow all of them, as you need to approve that one scope can read the data of the other scope.
