PS5 split screen not working in Realms

On 25 MAR 2026, my family attempted to play on our realms world. My wife and I usually play split screen on PS5 and my son on switch. My son could get into the game from the switch, but wife could not split screen with me. The game halfway loads and then goes back to only 1 player.

When switching to regular gameplay, split screen will work just fine, but not in Realms.
