[Mobile] Minecraft keeps crashing

Minecraft keeps crashing although i removed some of its cache but

Minecraft always crash whenever i Join a game but it seems that it generate huge amounts of cache in a matter of seconds, this only happens when i did interact with any command block or ANYTHING that has to interact with commands (example, NPCs, Command blocks, etc.) and sometimes the things that i have worked on now deleted, this also happens frequently and it will take hours or even days to finish my project.
