After Minecraft's logo appears, it goes to the title screen, makes a weird noise then crashes

This has been going on for months. I've contacted Mojang support TWICE the first they didn't even try to help, and now I'm here. This issue will never go away! I think I downloaded an addon that was corrupted or something. I wanna play with my friends. I tried deleting the app, getting rid of some storage on my ipad. Please help
