Photshop gpu compositing error

I’m getting an error message in Photoshop (27.4) When using the pureraw 6 trial (6.0.0 build 23) in any configuration (deepprime 3, compressed or uncompressed, deepprime XD3 compressed or uncompressed)

The error I get is “Compositing preferences auto-set to CPU due to an unexpected error. You can re-enable GPU compositing in your preferences if needed.”

I updated to the latest nvidia drivers for my gpu (RTX 4070 Ti super / driver 595.79.
The error remains.

With pureraw 5 I get no such error and the gpu compositing is fine.

I can process the same file in 5 and then in 6; the file from 5 will behave perfectly and the file from 6 will throw the error.

I can continue to process the files in photoshop but obviously its a bit slower not as smooth.

I have submitted a bug report to Support but wondered if anyone else was getting the same error
