Photoshop 25.6.0 - Create 3D Extrusion From A Layer

Hi all,

I am unable to extrude a layer to 3D, I can see there has been others post something similar to other versions - however, I have followed instructions on their posts and its not allowing me to do it.

One Was

Preference > Technology Previews > Check box on Deactivate Naive Canvas

This still didnt give me the option - if this is the way it should be done could someone advise the workflow i.e. how should you prepare the image so that the 3D option can be used as its still greyed out.

Also for information I am using Windows 11

i9 / RTX4090

Any help you can give would be greatly appreciated.

Thanks in advance.
