I'm having this issue, but i logged out of my singleplayer world while it was in LAN world mode. i either get Invalid player data while trying to get back in or  an error "Java.lang-" i don't remember this rest unfortunately.

Duplicating the world: Invalid player data.
New world, same seed: Invalid player data.
New world, different seed: works fine.

late, but it still happens, expect it continues after exiting f3, resetting or changing key binds doesn't help. nor can i figure out the previous solution as right clicking the launcher only brings up "close all tabs"

still an issue as it says 'missing dependency' and i personally don't have any lag, but everything from the addon is either invisible or doesn't show up at all even when the pack is activated.

i'm having a similar issue, my friend will try to send invites only for them to not go through or she cant send them at all. the other friends on the server were able to get the invites and join, but still experienced it once or twice while we were trying to figure why i couldn't get invites at all. i've had this happen several different times now.
