@Umija5895 Thank you for your reply! Let me know if my issue shared above is within the scope of this ticket. If not, please give me a pointer to a ticket that is more suitable for the issue. Thanks!**

The same issue has been happening to me and my family members who play in a common world on the realms server. I'm always disconnected from the server within 1 minute after logging into the server and everything is rolled back (+ some disappearance.) It's very annoying.

Originally, I thought the issue was some glitch on the Realms server, so I downloaded the world data from the Realms server and launched a dedicated server (https://www.minecraft.net/en-us/download/server/bedrock/) by myself that hosts the downloaded world so we can keep playing in the same world.

However, the same issue happens even when I logged in to the world running on the dedicated server as the same user (me). At this time, the dedicated server returns an error message that says the server crashed. So, it's not the issue specific to the Realms server but any Minecraft server with a certain version should have the same issue. This aligns with the fact that a family member whose character is not around the village (where my character is) does not have the disconnection issue when she's playing alone. When I logged in to the world and encountered the disconnection issue, she's also kicked out, which totally makes sense if the server process crashed.

Let me attach the error message FYI. I believe (hope) the bug report was automatically sent to the developer. I'm not a developer and I have no idea about those function calls. My guess is that, in my case, too many villagers & too many beds (+ some special condition) or something like that may be the main cause of the crash.
