Video Capture, USB connecting to a 2021 24 M1 iMac

Hi, Since upgrading to Sonoma V14, I can no longer use my Vid2Mac Capture leads. These are plugged into my JVC SVHS Player Output. It also has an S-Video, sadly the Digital output isn't available. (Being a former Dual Mini-DV to SVHS). I had been using OBS software to capture using the Video Capture Drivers EM28284 USB. Their new Driver was released on the 18th December, but doesnt install on my iMac (after giving permissions, re-install etc, Ive gone around in circles).

Being an ex Pro Film-maker, I have a unique Video Archive of world events, that I was starting to digitise and sadly now have come to an abrupt halt.

I would be eternally grateful for any thoughts.
