Genshin Impact Fontaine Bugs and Crashes on Android

I am a long-time player of Genshin Impact, and I have been experiencing bugs and crashes in the Fontaine region on my Android device. My device meets the minimum system requirements for the game, and I have no problems playing in other regions.

The bugs I have encountered include:

Trees and other objects are missing or incomplete.
I cannot walk on certain paths because the game thinks there is a wall there.
My character gets stuck on objects when I try to climb them.
The game crashes when I try to enter certain areas.
I have tried a number of troubleshooting steps, but nothing has worked. I have also reported the issue to miHoYo, but I have not received a response.

I am very frustrated with this issue, as it is preventing me from enjoying the game. I am requesting that miHoYo investigate this issue and fix it as soon as possible.
