Pokemon Ultra Sun suddenly freezes

Issue:
Suddenly freezes at some random point, or sometimes at some specific point, for example when I got my Rotompokedex from the Prof. and it talked to me the first time. Music turns into a weird noise which goes on and off every 1.5 seconds or so.
Edit: It happens everytime I start the game now.
