      This issue only happens with non-authorized versions of Minecraft, or otherwise modified launchers. If you wish to purchase the full game, please visit the Minecraft Store.
      We will not provide support for pirated versions of the game, these versions are modified and may contain malware.

      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!

      not sure whether is it because some files on my .minecraft file are corrupted, but it seems that it had something to do with launcher reading the library files

      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
