Screen and battery replacement but home button doesn't work.

So I was replacing the screen and the battery both parts from iFixit. I replaced the screen before on this phone without a problem but when I did the repair this time, the home button was not working but the Touch ID was. At the beginning of the repair after i powered it on to test function, the home button was working based on the taptic engine going off and it exiting apps but then pulled up an error and put in the digital home button and wouldn’t work after that except for touch id.

May or may not be relevant but when I would power up the phone and put in a password, the top right of the logic board where the top connector is would get very hot then cool back down. I don’t know if it is normal or not but just thought I’d add that information to see if it helps. Thanks!
