    posted a message on Twitch Launcher Modpack not Launching

    I am on a mac and I am trying to launch a profile (modpack) using the Twitch launcher. It is called Hermitpack 1.12.2 and it is the Hermitpack modpack (an official FTB modpack) but I updated as much as possible to 1.12.2. I press play and in the Game Output tab it says:

     

    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 full log is here:

    If anyone could help me that would be great. Thank you.
