Minecraft freezes on the loading screen before title

Minecraft is freezing on the loading screen before the title screen. Playing Minecraft isn't fun unless I can play it. It's been happening for months. It's been going on for so long I forgot which version it started showing up on.

What I expected to happen was...:

Minecraft would load and I would be able to play some of my worlds. I wouldn't be able to play on the servers/realms because of a different bug, but that should be its own report.

What actually happened was...:

It didn't go beyond the loading screen.

Steps to Reproduce

1. Use an Ipad Pro 2017 (though it will probably be hard to replicate since this is a bug that doesn't let you reach the title screen) on an older version from a few months ago. Update the software to IpadOS 13.3.1
2. Update the minecraft version. Again, the nature of the bug makes it unpredictable, but I'm fairly sure this is how it happened.
3. The loading screen that comes before the title screen will load for a bit, pause, resume loading, and freeze when there is one bar left to load, making the game unplayable.
