I'm trying to replace a world with a realm I just created but I am getting an error message every time I time and export and initialize the process.

I am on an Xbox one s with bedrock 1.19.31 the problem they I have is that when I replace a realm with the world I want I experience an error issue indicating that I cannot replace that world while I tried a world with less stuff in it(smaller world) I experienced no issue replacing that with the realm. There are no add ones and the specific error message is a black rectangle with error at the top and the text in the black rectangle is an error occurred
