LAN multiplayer doesn´t work; my partner can´t see any worlds available when I open up the world we´ve been playing on. Both of us are now on 1.20.5, the world updated to that automatically, the world was created on 1.20.4

Put the summary of the bug you're having here

What I expected to happen was...:
Open the world we´ve been playing on to LAN connection, so my partner can join in

What actually happened was...:
The world didn´t show up on my partner´s launcher

Steps to Reproduce:
1. I opened the single payer world from my pc
2. I clock "Open to LAN" -> start LAN world

3. The world doesn´t show up on my parner´s launcher, their pc is next to mine and they are connected to the same network
