Minecraft Crashes on Loading Screen

When opening Minecraft, the Mojang loading screen opens, and as the bar reaches almost 90%ish, the game stops responding. I have tried allocating more RAM to the game, reinstalling Java, and reinstalling Minecraft. I have also opened the output log to see if there was an answer there. I get a red message saying: "Process crashed with exit code -805306369". I have searched this error code to no results, thus bringing me here to ask directly for help.
