Minecraft won't start

Every time I launch minecraft it starts loading in and then it just re-opens the launcher and says the game crashed, I have tried updating my computer, updating java, un-downloading and re-downloading minecraft, and restarting my computer. I have a windows 10 computer and I downloaded the minecraft for windows, the game doesn't start up at all it just closes the launcher and re-opens it with the crashing message, I honestly have no clue what could be wrong.
