      This issue has been reported before but is incomplete without a solution, however i have the same issue. This is what pops up when it fails to open:

      https://gyazo.com/4b5884f09415ec7b7910477032b8f5b3

      although I have found the latest log for the latest release (in this case 1.13.2) but I'm not sure what I should do with this information. here is the pastebin:

      https://pastebin.com/aCTpMzGA

      Launcher version: 2.1.1432 

      Trying to launch: Latest release, 1.13.2

      also here is something i have noticed: each time the loading bar appears, it ends abruptly, as if it failed to unpack something, this happens about 3/4 of the way in the loading bar.
