Nintendo switch error 2101-0002 Unsure of the issue

i was playing animal crossing one day it errored with 2101-0002 and i hard reset since it froze it never turned back on the usb c port was replaced way later by ubreakifix because the oval shape was looking a little spilt a tiny bit in the middle that didnt help so i wasnt charged but i still dont Understand that error nether Does nintendo smh any clues on what it could be related to?

I would guess there is an issue with the M92T36 chip.

What Chip is that ? What does that do ?

It is part of the charging circuit, I think it is the chip that communicates with the charger to request either 5v or 15v.
