Unable to load my biggest world ever made, problem persisting several times, even after deleting the game

I try to load my world that I play the most and the message appears that the resource pack is loading, then the message appears saying that this world could not be loaded. When I make a copy, sometimes the world loads but the game crashes, other times a message pops up quickly with a purple and black checkerboard background and automatically exits the game. This never happened before. Interestingly, the other worlds where I don't have anything good, they don't crash.
I tried deleting the game and redownloading it with the cloud downloaded worlds, but the result was the same as before. The resource pack I use is the Sonic Texture pack, developed by Gamemode One, I already tried to remove this texture from the world and the game and even so the problem persists.
