Home Button and Touch ID not functioning

So I was doing a screen replacement on an iPhone 7 today. Have it a couple 30 second bursts of a hair dryer just to loosen the glue. Put my pry tool in and started to gently work on the bottom left hand side of the phone. I had the screen pretty much pried off when I accidentally hit the power button and the phone turned on, when it turned on I got a message saying that the power button needed servicing and the assistive touch thing came up on the screen. I continued with the repair, everything works perfectly apart from the home button. I have tried it on the old screen, not working there either.

I know logic says I did damage but I have looked and looked at the home button and ribbon cable and cannot see anything wrong with it. All I had done when I got this message was open the phone. I’m not a rookie with either, I have replaced upwards of 100 screens on lots of different iPhones. Am I goosed here?
