    Description

      Hello,

      when trying to launch some modded versions of the game, including all of the OptiFine versions I own, the launcher or the game instantly crash.

      This might be due to invalid arguments in the Java command when the game is started:

      (Sorry for this being German, it just means "use")

      Please note that this only occured in the latest beta version of the launcher, meaning there must be some kind of issue going on inside of it which causes this error.

      Here is how it plays out:

      • The game dosen't actually open, however it starts printing in the log
      • After that, the error about how the right use of the javaw command shows
      • At this point, it may just instantly exit with a -1 exit code or the launcher might just think everything is fine until it suddenly crashes without anything to go by

       I could only find this issue in OptiFine versions of mine, but in every single one of them. Other people I asked also had this issue with their OptiFine profiles not starting anymore.

       

      Hopefully this kind of issue gets fixed, thank you.
