Yes, it only works in the hekate menu
If it doesn't work in Stock OFS/Sysnand mode it's a wonder that it works at all in Hekate. There's going to be very little to troubleshoot here. It's quite possible you will need to take it in for repairs. Here's what I can think of off the top of my head from least invasive to most invasive:
1) go to Settings > Test Input Devices and see if it responds there.
2) got to Settings > System Settings > Controllers and Sensors -> Touch-Screen Sensitivity and change the setting to just see. (You will eventually want to end up on Standard but the idea is to change it to anything to see if we can get it to work.)
3) upgrade firmware to the latest version (14.1.1). If it's already at latest, downgrade to 14.1.0 and then upgrade. (Again we're just trying to get something to work here.)
4) take it in to a reputable electronics repair shop.
