Hi! I created a minecraft launcher, but when I tried to start the game, I got this error message:

Exception in thread "Thread-5" java.lang.NullPointerException at java.lang.ProcessBuilder.start(ProcessBuilder.java:1012) at fr.theshark34.openlauncherlib.external.ExternalLauncher.launch(ExternalLauncher.java:155) at me.bence.hu.Launcher.launch(Launcher.java:50) at me.bence.hu.LauncherPanel$1.run(LauncherPanel.java:171)

Code: https://pastebin.com/41qz4NUQ Minecraft version: Vanilla 1.16.5

Could someone help me?

Regards, Bence
