Split screen not loading on Nintendo switch device.

Are your joycons/Controller charged? They may have low battery.

Also affected. Adding details that may help narrow this down.

Platform: Nintendo Switch 2, native Switch 2 version, 26.60. The same issue also occurred on the Switch 1 version (running on Switch 2) before the native release.

Steps to reproduce:

1. Create a new world with default settings

2. Load the world as player 1

3. Join as player 2 with a second controller (+ button)

Result: Split-screen appears for about a second, then the game exits the world and returns to the world selection screen. No error message, and the app doesn't close.

Key detail: this only happens in newly created worlds.

• 100% reproducible on every new world, including one created immediately before testing.

• Worlds created on the original Switch earlier in 2026 still work in split-screen on the same console, same game version, same controllers.

Timeline: Started in August–September 2026 on the Switch 1 version, after the 26.40/26.50 updates. Still present in 26.60 on the native Switch 2 version.

Possible cause: 26.40 and 26.50 introduced behavior gated on a world's base game version (e.g., stair corner and thin-fence/trip-wire connection-state neighbor updates that apply only to worlds created on 1.26.40/1.26.50+). That matches the old-world/new-world split exactly. This is a guess, but checking whether split-screen client sync fails on worlds with base game version 1.26.40+ may be a quick way to confirm.

Troubleshooting already tried, none of which fixed it:

• Reinstalled the game directly onto the console's internal storage

• Fully uninstalled and reinstalled the game

• Cleared all game cache

• Removed all other games from the console

• Restarted the console

• Lowered or turned off all graphics settings

Workaround: Playing older worlds (created before 26.40) in split-screen works.
