I have an attachable gaming controller on my device (which is an IPad Air 3rd gen.) and i have noticed that in the first few minutes of gameplay, it works perfectly. Then, it goes through “waves” and glitches to the point where my screen freezes. It is odd because my controller is newer and has never given me issues before.

I think nothing of it, maybe it is the controller. I disconnect it and play without it, and it does the same exact thing; the game play is lagged and it freezes every other minute. I checked for updates and there are none available. It happens the most when I sprint. I have played with and without internet; the situation is still occuring.
