Game Crashes Immediately Whenever I Open It, And Launcher Doesn't Like To Work Sometimes.

Whenever I Open Minecraft, It Immediately Crashes. It Only Works Once A Month, Or 2 Times A Month. Anyways, It Says That While It Was Trying To Open The Game, It Crashed. This Has Gone On For Three Months. I Am Starting To Think That The New Launcher Either Hates Me Or Is Just Trash In Terms Of Actually Working. Speaking Of The Launcher, For The Past Four Weeks, It Hasn't Even OPENED. I'm Starting To Think That The New Launcher Is Pure Trash And That Mojang Should've Kept The Old One. Or, There Should Be An Option To Go Back To The Old, Non-Glitchy Launcher.
