[Identified] We are currently aware of an issue affecting a small number of customers who are unable to open both the Workflow and Forms designers from the SharePoint ribbon bar, when using the Modern experience. The workaround is to revert to the Classic experience.
Nintex have reported the issue to Microsoft and will post an update as soon as one becomes available.
