Did you change analog carefully? You could damage solder tracks or points. And another reason it can be button flex board - make sure it contacting good with the main board

Without the daughterboard connected the controller can do all kinds of weird things.

Post a pic of the top side of the board, there is a Pull-Down Resistor that needs to be on there to keep R1 off until it is pressed. If that were knocked off the board or damaged it could cause that issue.

Yeah it's missing. Replace that and you'll be good to go.

It's a 100k, 0402 size Resistor.

I fixed it

But hardly because  100k, 0402 resistor is very very small

Thanks again for solving my problem
