Next Generation External Supplier Registration Stuck/Error status

Summary:

We are using next gen redwood supplier registration.
We created a supplier in Germany BU, Approved the supplier rgistration but the supplier creation finished with Error:
The Bank account number parameter field isn't populated. Check the application setup. (IBY-825205)

Supplier reg was already approved. It seems there is some issue with IBAN Number as bank account is null, was not derived. How can we correct that error? no option to edit the bank account details. we are stuck. There is no action to correct or even return the registration to supplier after the registration was approved.
