Crashes since beta version 1.20.20.20

The game crashes very frequently on high-end cell phones. It's been 5 months since Mojang hasn't resolved this problem, which by the way is very serious. This has been happening since version 1.20.20.20. I believe it was something that they changed in beta 1.20.20.20. From that version onwards, several delays and crashes started to occur on Android devices. I ask you to evaluate what was modified in this version to solve our problem, it is impossible to play with these crashes.
