Minecraft doesn't open

Minecraft is not opening at all, well, the launcher does open, but it (according to the Minecraft Launcher) "crashes" every time i try to open Minecraft, it doesn't even open for a split second before crashing, it just, "crashes", you would think i would be excited about 1.15, but since it crashes, its just plain boring. Please fix, thanks.
