@Kat Vinden,
Are you running the In-Browser Session on Ansys Cloud Direct as shown in the Knowledge Base (KB)? Which version of Lumerical are you using on Ansys Cloud Direct? >>> Lumerical on Ansys cloud – Ansys Optics
Try to open/launch a new in-browser interactive session using the Lumerical 2023 R1 release on Ansys Cloud Direct. Then open the CAD from the launcher as shown in the image. (taken a few minutes ago on Ansys cloud direct)
Or directly from the Windows Start Menu
