Desperate for a Ring Door Cam Flex cable

I'm in need of a Door View Cam flex cable but this spare part has been out of order on the Ring site for a very long time.It is available in the Netherlands but they don't send products to the UK. I need to try replacing this piece as a first step toward understanding why my Ring Door bell isn't working and don't want to pay the crazy prices listed on line. Hopefully someone has a spare. I'd be extremely grateful.
