If you have already purchased the game, you should redownload the launcher from here; if you prefer the older launcher, you can download it from the alternative download page.
I have not been having an issue with the Minecraft launcher only until today, whenever the launcher starts to unpack its natives, it encounters a fatal error.
17:43:36 FATAL]: Fatal error launching game. Report this to http://bugs.mojang.com please!

like I said previously, it was working find until today, so it wasn't hardware related, since I hadn't modified any of my drivers. I've updated java and reinstalled the launcher a few times after I got the message and unfortunately, there was still no fix, still displays that message.
I am unable to switch over to an exe launcher by the way due to reasons.
Is there any way to fix the bug? Please respond as soon as possible, since this bug makes it impossible to open Minecraft

This does not only happen in the cracked launcher, but also the official 1.6.84j launcher (or the old launcher. I hope this gets fixed, because I like to use the old launcher!
Try redownloading the old launcher from here. Does the issue persist?
Thank you for your report!
