I can't exactly point what is happening. I've never encountered a case like this.
But I suspect it may be an Android IME/keyboard resize/inset bug causing Ren'Py's touch-coordinate area to become wrong.
In English: It might have something to do with your keyboard. Does something change if you rotate your phone 180?
And, do you perhaps have any accessibility setting on your phone that might affect it?
That's my only clue. I'm not sure what else it might be.

When I rotate the phone, the game doesn't follow with me, it's stuck in one way. But when I was playing yesterday a few hours after my comment I noticed that when I went to the homepage on my phone and came back to the game without closing it, the ability to click came back for whatever reason, I forgot to update after the discovery but I don't know how it can even be fixed. Hopefully when the next update drops it will fix itself
