Game freezes for a few seconds when switching the camera

Please fix the Mojang freeze bug. Players are really struggling and frustrated with this issue. Every time I switch the camera using F5 or F1, the game often freezes for a few seconds. And it’s not just that—when playing in survival mode during critical moments, this bug becomes a real hassle. I've died several times—actually, many times—just because of this bug. Please fix it!
