I can't see the block or the entity

My Minecraft Bedrock 1.14.60 was normal yesterday,but today, when I join the game, I found that the screen was blank. I could only see the UI, hear the sound, and open the backpack. I couldn't see the block or the entity.The blocks in front of me are all glass, transparent, but the containers like chest can be opened. Zombies will attack me, but I can't see the zombies.Some people say it's about the anti-aliasing setting. They asked me to turn it down, but I didn't see the anti-aliasing option in the setting.

I hope the official can deal with it as soon as possible. I really want to play.

Thanks.
