Look direction, chests/inventory broken, Extreme stutter, and realm crashes

I'm experiencing nothing but issues with Bedrock Realms. For context, my ping to the server hovers around 18ms, and my Wi-Fi speeds are consistently 200-300mbps. Just today, I noticed my look direction jumps around to random directions. I don't believe this is lag, as it happens even if I'm standing still for long periods. I've tried a different mouse, and it still happens, so I think this is an in-game issue. Over the past weeks, I've noticed the realm itself is extremely unstable. I'm occasionally getting kicked and can't get back in for 10-15 minutes. When I can play, I have very bad stuttering, blocks won't place, and my position stutters when running. Often chests and inventory will stop working. I can trigger the open animation on like 50 chests, but it won't open their inventory, and I can't open my own, so I have to quit and rejoin. Bedrock is supposed to be the better modern platform. I’ve been patient for years, but ‘bugrock’ continues to live up to its name. Every update introduces new performance or stability issues that make basic gameplay frustrating. Markus built a more stable game in a cave with a box of scraps. Why can’t the biggest tech company in the world keep a 13 year old, #1 best selling game from falling apart?
