Minecraft won't launch.

Up until a few days ago, my Minecraft, Java version, had been running fine. However, now whenever I try to start the game, the launcher will load until it's almost completely done, then become unresponsive and completely crash. I've made sure to delete any mods, resource packs, or anything else that would be modifying the game, yet nothing seems to work. I've also deleted and reinstalled the game, which did nothing. If there's anything else I could try, please let me know, as I don't know what else to do. Thank you for your time.
