Problem with external GPU on Mac (Intel)

[PawelKohlsRCM]

Hello, 
I can't run Fusion with "Prefer External GPU".
I get only grey screen.
Does somebody fixed this problem?
I use Sonnet case + Radeon RX 6800 + MBPro(with intel processor) (Ventura 13.1)
Below screens with the issue.

Thank you.

Thanks for posting. At this time, external GPU is not supported in Fusion 360.
