@netiahkj Did you install Opitfine through the Addon Marketplace in Aristois? I think that may be the problem since Optifine doesn't work for me when I've installed it.
I found this thread: https://discuss.aristois.net/topic/13/how-to-uninstall-optifine-optifine-error-on-startup
It shows you how to uninstall Optifine.
