Looking for someone here to take pity on a mom who has scoured the internet trying to resolve this error to no avail. My kiddo and I are trying to use Twitch to play Minecraft Modpacks and every time we launch the game we get the error below. I've uninstalled and reinstalled Twitch and Java a million times.
We are using a Mac running macOS Mojave version 10.14.5
GameOutput says this: 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: java.base/jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to java.base/java.net.URLClassLoader at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28)
The end of the Launch log says this: [19:51:51 ERROR]: java.io.IOException: Stream closed [19:51:51 ERROR]: Game ended with bad state (exit code 1) [19:51:51 INFO]: Ignoring visibility rule and showing launcher due to a game crash
