@chandan-naik-rupeek This is a known issue on Windows only. Sorry for this, we'll try to fix it these days. It's a problem with the USB descriptors on Windows, due to addition of the UVC interface, the XLink VSC interface no longer works to send the depthai pipeline to device.

Is there any other method using which I can use the OAK as a uvc device?

Yes, in the meantime using a loopback device in Windows likely should work: https://docs.luxonis.com/en/latest/pages/oak_webcam/
