Mouse movement is delayed

Every time that I move my mouse to look at places in Minecraft, the movement is so delayed (See Video). It also happens when I'm changing settings. I started today 12/10/2020. My Brother and my friend have been having the same problem. I have looked up how to fix it, I have uninstalled and reinstalled Minecraft, I have restarted my computer and tried everything and I cant fix it. And it has lowered my frame rate.
