The main page of this site says "If you're reporting bugs you've found in our Minecraft Launcher, you can do so here." Please go to https://bugs.mojang.com/browse/MCL or try contacting support (if there even is support).
Are you sure you're in the same exact version/snapshot as all of your other sisters? I don't think LAN worlds support users with different versions. You should take a screenshot of the problem so it can be better understood.
