Cubase 15 Pro Error on Synth V 1

Posting this for info for Devs as much as anything, as I can’t see Dreamtonics spending any more resources on V1. However, just a warning for anyone that has old Cubase projects with the V1 app and ARA extensions - I am getting this error everytime I load a project with V1.

To get around it I need to export the V1 project to an external file, then import it into a V2 instance in the Cubase Project after removing the V1 tracks.
