Sudden Sensitivity Changes

My DPI is 800, Sens 2.5 ADS 1.0

The game works perfectly fine as it should be, but my sensitivity often feels different when jumping into a game. Normally what happens is my sensitivity works as it should, and as a reference I swipe my mouse from the middle of my mousepad to one end, which should turn my character a little over 180 degrees. When my issue occurs, my sensitivity lowers, and when I swipe my mouse from the middle to one end, my character doesn't turn 180 degrees. I don't know what exact sens it changes to as it is always random, but it is definitely way lower than 2.5 sens. This happens to me mostly in the early game of a match. I always try to swipe my mouse to one end of my mousepad as a routine throughout the game to see if the problem comes up again, and so far I've only noticed it happening during the beginning of a game, and rarely during the end. My FPS is stable and stays around 70-100 frames, which may seem like an issue as it could cause input lag, but I know for a fact it is not the problem as during Season 1 or the early days of Apex, I have never had this sensitivity change problem, and nothing about my system has changed since then.
