When I did that, it wouldn't let me enter that world (I only have 5 worlds), but it wouldn't let me enter that specific world, and I get this error. Can this be resolved?

Hello Mojang, I would like to report this issue with the Minecraft game bedrokc. With the new game update, I can't play my world. Recently, the game asked me to delete some files because I didn't have enough storage to save my world progress. When I did, I tried to re-enter my world, where I've been playing for 3 years and have made progress. When I did that, it wouldn't let me enter that world (I only have 5 worlds), but it wouldn't let me enter that specific world, and I get this error. Can this be resolved? Because I really want to continue playing that world I've been playing for years. I have proof of the error.
