@ChampionAsh5357 java 8 and 1.8.9

Java 8 and Forge 1.8.9 This exact setup worked on windows 11, then i downgraded and it doesnt work no matter if i do it the same way i have done or a new way

Hello, I get this error when trying to run the client Exception 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)

But I used the exact same setup 3 days ago and it worked perfectly fine

Whenever I'm trying to run my mod, it says "Error: Could not create the Java Virtual Machine \n Error: A fatal exception has occured. Program will exit", while the console says "Unrecognized option: -Xincgc". I tried to reinstall Java, creating a completely new Mod (because I may have lost some files due to downgrade from win11 to 10, i thought this was the issue, it wasnt.) and it still gives me this error.
