I cannot connect to friend's realm, it shows error "An error occurred, please try again later." after reseting the realm.

After my friend reset his realm, when trying to join, it would eventually come up with the message "An error occurred, please try again later."

What I expected to happen:
To join the realm successfully without issue.

What actually happened:

It showed up with the error message "An error occurred, please try again later." after a few minutes.

Steps to Reproduce:

        - Terralith

        - Nullscape

        - Incendium

        - Lifesteal Datapack

2. The world uploaded successfully, and there were no issues

3. Wait a few minutes, and the error should appear
