I cannot get the Astra Pro camera to work with Unity on Windows

Hello,

I am trying to get a program built with the Astra Unity package to work on my computer (Windows).
The Astra Pro camera does not seem to respond at all. I get the following error :
AstraException : astra_imagestream_request_modes :
Invalid Operation.
I tried to uninstall/reinstall the drivers several times but it still does not work. I am completely stuck here.
Could you please help me?

Im not sure that IMAGESTREAM is a currently support usage case for the ASTRA PRO. FWIW - I would stick with the ASTRA or ASTRA S for depth based work at the moment
