Keeps kicking from game "out of data storage space"

When I load in my world I can play for about 5sec then I'm kicked out and told

there's not enough storage space and Minecraft can't store it. I've cleared cache
and deleted all my old worlds with 75GB of space on my phone. I've tried sending
the world to my realm but it won't upload to the server. I really don't
want to lose my progress in my main world so please help.
