Lads and Ladies, My issues are that when I launch Minecraft, the program Java (TM) Platform SE Binary takes more than 6 minutes to load. This did not happen before. I have Nvidia 850M and Intel Core I7. I also have 8GB of RAM.  

The second issue is that I cannot join any world or server. It is stuck on the loading screen for both. When I launch a singleplayer world, the game freezes completely. When I create a world, it also freezes. When I join a multiplayer server, it can still be left. I have tested with every server and it is the same results. 

I don't know if there is a correlation between those two. Please help, I cannot play otherwise.
