Im using Twitch and pressed play on the Kinda Crazy Craft Modpack and then it redirected me to the old Minecraft Launcher. Then when pressing play this showed up:
Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option PermSize; support was removed in 8.0Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option PermSize; support was removed in 8.0Exception in thread "main" java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28)
I tried playing normal 1.14.1 then playing the modpack but it also didn't work
I tried installing the java on the link in Twitch>Settings>Minecraft and then it also didn't work.
