The last time I played Minecraft on this computer was 4 years ago, I think around version 1.12. I decided to fire it back up again but I received a "Fatal Error In Native Method" and received "Error Game Crashed". My Minecraft Launcher for the most part "looks" up to date. I've been trying to figure out what the problem may be:

-I deleted my old application and redownloaded it from the website.

-I restarted my Mac 5 times

-tried shutting my desktop down

-updated my computer.

-I deleted my old files from my Library.

-I even tried logging out and back in of the Minecraft Launcher. 

-I don't have Minecraft Dungeons/Realm

I know that trying to find the source is difficult and hopefully this is enough evidence to help, but I would really appreciate it if it can be fixed, thank you very much!
