Extreme visual glitches when playing Minecraft Bedrock Realms

I was just playing my friend’s Minecraft Bedrock Realm as normal until I left and joined back, where I was met with a variety of extreme visual issues.

One of the first being that upon entering first-person view, my screen was completely black apart from my HUD, the paperdoll, and for some reason my own character that I was able to partially see when walking around in first-person.

Another extreme visual glitch that occurred was the fact that the main hand of my character is spinning around and moving extremely abnormally, alongside the actual item my character is holding proceeding to move and flicker in erratic ways.

I had also noticed that in the video attached, the wandering trader’s llamas were completely missing their texture, appearing pink; and the animation for the cats sitting down in the same video appear standing up, but the legs being very misplaced.

I am not sure what caused these glitches or how to reproduce them, because all I did was rejoin the realm which had seemed to start these visual bugs.
