Xbox live causes intense freezing and crashing

my Minecraft has been freezing to the point where I have to restart my laptop by holding down power button down.When Minecraft boots up everything is fine, I can navigate the Minecraft home page through store and settings very quickly that is until Xbox live auto signs into my game.It instantly freezes the game to the point I dont even have control over the pc and keyboard shortcuts such as ALT+F4 dont respond to anything. I tried loading up a texture pack ive downloaded from the store though the download completed fairly quickly, the importing was stuck at 19% and it was on for about 15 mins (it usually takes like 20 secs). I knew Xbox live had something to do with this bug so I navigated myself to the "com.mojang" folder deleted everything inside the folder this stopped it from auto signing in and everything worked spotlessly menu gameplay and all but as soon as I tried to sign in to play multiplayer I was back at square one

 

I consider this a game breaking bug and would appreciate a reply thanks.
