Hi Ciaran,
We’ve not had any reports of emailing issues that would be related to the current release.
According to the error message, the electronic document properties need to be set in the customer parameters, which relates to standard SSRS.
Microsoft’s documentation mentioned electronic document properties in this link: Customer electronic invoices - Finance | Dynamics 365 | Microsoft Learn.
Could you check their official documentation, adjust the setup, and let us know if that solves the issue?
