Failed apply mixin to ObfuscationReflectionHelper with `MixinTargetAlreadyLoadedException`

I'm mixin into ObfuscationReflectionHelper in my mod. But VintageFix breaking that with MixinTargetAlreadyLoadedException

VintageFix/src/main/java/org/embeddedt/vintagefix/core/VintageFixCore.java

Lines 81 to 87 in 22b5d1d

    
           ObfuscationReflectionHelper.findField(LaunchClassLoader.class, "packageManifests").set(cl, new ConcurrentHashMap() { 
        
               @Override 
        
               public Object put(Object key, Object value) { 
        
                   return null; 
        
               } 
        
           }); 
        
           Field resourceCacheField = ObfuscationReflectionHelper.findField(LaunchClassLoader.class, "resourceCache");

The fields on the CL won't be obfed. It's launch wrapper instead of the game itself.

And also

Does 803605a help?

It does

	ObfuscationReflectionHelper.findField(LaunchClassLoader.class, "packageManifests").set(cl, new ConcurrentHashMap() {
	@Override
	public Object put(Object key, Object value) {
	return null;
	}
	});
	Field resourceCacheField = ObfuscationReflectionHelper.findField(LaunchClassLoader.class, "resourceCache");
