Sometimes, during multiplayer, all participants are forcibly disconnected

During multiplayer, all players except the host are forcibly disconnected from the server. The world does not shut down; only non-host players are disconnected. Restarting the world and Minecraft does not resolve the issue, and it can occur repeatedly within a short period. The number of players at the time was around 20. When the issue occurred, I checked the internet connection speed, which was approximately 100 Mbps. This is just my impression, but I did not notice any lag and felt there were no particular issues with the host or the world.

 
I hope for an early resolution to this issue. Thank you for your attention.
