Achievements turning and multiplayer turning off randomly even if wifi connection is okay

The encounter started when i was trying to invite a friend over to my world, it did work at first but when we did again after a few minutes the multiplayer settings had been turned off and the achievements had been turned off aswell, the world is a hardcore world so it possibly cant be from cheats, and it had no mods or addons so it didn’t cause it. I believe its from the game’s code error and the account because my skins wont show still i hope this bug gets fixed
