Thank you for your help. I'm playing multiplayer, but this time it won't start, so please let me know.

One of the multiplayer games has finished, and after starting it up, I played alone on the island, and then from the first screen, I thought I'd try something other than Adventure, so I went into the game in the upper left and clicked on an island, but I didn't know what it was, so I pressed the ESC key to return to the first screen, and tried to end it by clicking on the ✖️ in the upper right, but the 🌀 kept going around and around and didn't end, so I forced it to end from the Windows screen. I started YLAND again from Steam, but the attached image appeared and it became difficult to start. I uninstalled YLAND, installed it again, and tried to start it, but the same problem occurred and it didn't work.

I tried to start it from another multiplayer account on a different PC, but the same problem occurred and it didn't work.

I can't do it at all, so please tell me how to improve it.
