Hello, when I use Photogrammetry, I receive this error:
Error creating session: cantCreateSession("Native session create failed: CPGReturn(rawValue: -11)") .

My specs are listed below. I think My macBook Pro should be supported. Please let me know if I missed something or if there is a fix for the issue.

The CPU and RAM is okay for creating session but key part is GPU. Your GPU needs to have 4 GB of VRAM. If it has 2 GB, it will not work.

as @unibodydesignn said, your GPU doesn't meet the minimum requirements...

Curious though, are you getting this "-11" error code on Monterey Beta 1, Beta 2 or Beta 3?

... as I too got "-11" on Beta 1 ... though after updating to Beta 3 ... I'm getting a "-21" ... (thinking same issue, just that they updated the Error Codes list between the different Beta's ....)

My "-21" issue ... and asking the devs for a complete list of error codes to be added to the API Documentation, so we don't have to ask everytime. https://developer.apple.com/forums/thread/685208?page=1#682368022

Monterey Beta 2. I upgraded to a mac mini with an M1 chip, and I am able to create 3D models with the photogrammetry api.
