My survival world started to bugging. Bugging includes chunks flashing and disappear of HUD. I checked multiple times for Hide HUD option and tried cleaning caches for at least 3 times. Even I backuped said world and cleaned all datas. I booted my device at least 5 times. I tried to copy original world and tested the clone, all the bugs remains. I have an storage space over 1 gigabyte since my phone (G3 Stylus) is 8 GB.

Other world's HUD and chunks works properly, i tested them. But only problem is with my survival world.

Edit: I noticed that chests and entities (mobs, armor stands, dropped items and chests) are invisible too. I dont know why
