Hello. So I got myself a used LG V20 last week, installed LineageOS 22 on the 11th of this month. Everything works well (Wifi, charging, thermals, etc). Then yesterday (15/10) at evening I noticed the battery percentage suddenly stopped climbing, stuck at a percentage and never climbed higher. I leave it to charge a few more and still not increasing, infact the percentage actually goes down. In the settings app the battery is labeled "Not charging" and a reliable diagnosis app showed "Discharging" even tho the cable is plugged in.
And yes I did try a different cable, different charging brick, different wall plug -- also cleaned the charging port and the battery contact pins, nothing changed.

Weird thing is when I boot up in TWRP the battery can actually charge there. In the meantime I reinstalled Lineage 22 again (wiped everything beforehand), and it still didn't help. Could it be hardware or software issue and is there a way to fix this? This is my first time rooting a phone so any help or suggestions is appreciated
