Can’t load my world

I cannot load my world.

When I try to load it up it says “there was a problem loading this world”, almost immediately.

My world is 900 MB.

I assume it’s unable to load because of the size.

I delete the world and downloaded it from the PlayStation cloud and it still won’t load.

I deleted Minecraft and it did not work either.

This has happened many times before, I don’t understand why this keep happening ONLY to this world.

This is the only world I have on Minecraft so I assume it’s not a storage issue?

I’m at a loss and I don’t know what to do.
