### Describe the Bug

when trying the new method for capturing the screen i get an error:
Error: Screen capture is not supported on this device for this release of Windows: failed to acquire device: [0x80070424]

this is the only error shown in the logs. its shown multiple time and followed by:
Fatal: Unable to find display or encoder during startup.

when trying the following sample app on my computer it seems the API itself is working fine

i am not sure if this the exact same way implemented in sunshine. but in this sample app the xbox gamebar is also shown in the capture.
thanks
