Check U9 controller on a board. On output should be 1.4V. I have a solution but it's not very nice. Connect output trace with 3.3V. It worked for me but I don't guarantee that it will work for a long time. You could also replace this IC. Problem is that it's a very small piece and it is easy to burn using hotait. Sometimes this IC doesn't have any specifications on it (especially in 1708 and older) so proper resoldering it can be quite tough

do you mean inject voltage on the trace to fix it?

Yes. It helped. I don't remember where specifically I connected it, it was a long time ago. Maybe before a voltage divisor if there was. I remember that those sensors have common power so if there is no power, they both don't work.

I just came across this problem on LT and fixed the problem by replacing the U11 component (303 hall effect sensor for the trigger) with an old xbox one controller 304 hall effect sensor.
