The game won´t launch and kept crashing

This isn´t the first time I reported this issue. Its been 4 times reported by me.

Every version before the 1.15 (The bee update), runs my iPad smooth. But when the update 1.15 was released there came the problem. When after I updated to 1.15 and simply launch the game and… The game instant crashes. Everytime when i try to launch the game. I restarted my device and it didn´t solve evrything. Untill now it still doens´t launch and kept crashing. I waited and waited to update the game but, every update didn´t solve my problem. The option now to maybe solve the proble is: delete the game and re-download it. But there is a major problem then, I lose al my worlds. I don´t want to lose all my worlds especially after the progress what i maded. Is there a way to recover all my worlds? Please notice I CAN´T simply launch the game so answers which requires to launch the game doens´t work. Also i don´t got a bedrock account so that´s also a problem.
