I could not do "Replace world" from switch

I used "replace world" from my switch. Error message appear every time.

Even error message will appear, sometimes i can play it.

However the world I want to use is large file(44MB).

This world could  not play. I've checked previous issues. Has this issue has not resolved yet.

This is a critical issue for users. I've contracted 2 realms and realms plus. Could you please resolve this issue.
