Photoshop 3D Extrusion - Settings Non-Responsive, No Mesh

Hello all, 

Last week, I worked with 3D extrusion and all was well. Well... not anymore 😄 

Today I wanted to work on another project - so I created some text, went to the usual 3D - Create 3D Extrusion from selected layer. One of two things happens: 

• the text/object disappears simply (it does not matter what settings I change within the 3D workspace, its just gone)
• the object remains but I can not adjust anything in any way - changing settings has no effect on what I see on the canvas.

The odd thing - If I create a text layer, say, with the word 'Hello', run the 3D extrusion, run into one of the results above, delete the text layer and create a new one with the word, say, 'Again', click on 3D Extrusion ... the word 'Again' disappears and the word 'Hello' reappears. If I reposition a layer in the layer panel and switch back to the 3D panel, the layer snaps back to its previous position, unchangeable. 

It seems like the 3D Extrusion is simply 'stuck' - I don't even see a mesh, nor can I change settings on the camera or the environment - just nothing happens. It also seems like some parts of the 3D workspace are somewhat missing 😄 Anyone had this issue before? 

Things I tried: 

• Checked OpenGL is enabled
• Switched to 'Basic' Performance operation
• Restarted Laptop
• System Update (MacOS BigSur 11.3.1)
• Re-installed Photoshop
• Reset Photoshop settings 
• Tried to use shapes/anything really instead of text, tried smart objects
• Clicked on EVERY setting available within the 3D workspace to try to narrow down the problem - nothing changed/was visible

I would appreciate any insight you might have - thank you!
