ManyCam does not receive video input from Sony 7C Camera

I am having an issue with one of my camera input. I have an external camera which works well with all platforms such as Zoom or MS Teams or Google Meet, however ManyCam is not is not opening this camera. When I try to use this camera as video input source, it gives me “Time Out” error message. My camera is Sony Alpha 7C and I am using it as a webcam. This camera is very important to me because other webcams’s video quality is not good. I use it with all other apps without any issue. I do not know why only ManyCam is not working with it. Any suggestions will be very much appreciated.

Manycam support is not very helpful. I had brought this issue to the attention.
