I want to get into AA but I can't find any tutorials on it. Does anyone know of a good way to learn AA?

Im using OBS and Specnr's setup^^^^

I used Specnr's tutorial and it works fine, but sometimes it won't go into the F3+Esc menu when I reset and that instance won't reset until the default S & Q menu goes away and it is fully loaded. Any tips to fix it?

Don't know if I need to post this but: [07:23:33] [Client thread/ERROR]: Minecraft has crashed! net.fabricmc.loader.impl.FormattedException: java.lang.ExceptionInInitializerError at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:463) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.Knot.launch(Knot.java:74) [fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClient.main(KnotClient.java:23) [fabric-loader-0.14.14.jar:?] at jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:?] at jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) ~[?:?] at jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:?] at java.lang.reflect.Method.invoke(Method.java:568) ~[?:?] at org.multimc.onesix.OneSixLauncher.launchWithMainClass(OneSixLauncher.java:214) [NewLaunch.jar:?] at org.multimc.onesix.OneSixLauncher.launch(OneSixLauncher.java:249) [NewLaunch.jar:?] at org.multimc.EntryPoint.listen(EntryPoint.java:143) [NewLaunch.jar:?] at org.multimc.EntryPoint.main(EntryPoint.java:34) [NewLaunch.jar:?] Caused by: java.lang.ExceptionInInitializerError at net.minecraft.class_3268.<clinit>(class_3268.java:82) ~[client-intermediary.jar:?] at net.minecraft.class_1066.<init>(class_1066.java:61) ~[client-intermediary.jar:?] at net.minecraft.class_310.<init>(class_310.java:351) ~[client-intermediary.jar:?] at net.minecraft.client.main.Main.main(Main.java:155) ~[minecraft-1.14.4-client.jar:?] at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:461) ~[fabric-loader-0.14.14.jar:?] ... 10 more Caused by: java.lang.RuntimeException: Mixin transformation of net.minecraft.class_758 failed at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.getPostMixinClassByteArray(KnotClassDelegate.java:427) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.tryLoadClass(KnotClassDelegate.java:323) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.loadClass(KnotClassDelegate.java:218) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassLoader.loadClass(KnotClassLoader.java:112) ~[fabric-loader-0.14.14.jar:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:520) ~[?:?] at net.optifine.reflect.Reflector.<clinit>(Reflector.java:197) ~[Optifine-mapped.jar:?] at net.minecraft.class_3268.<clinit>(class_3268.java:82) ~[client-intermediary.jar:?] at net.minecraft.class_1066.<init>(class_1066.java:61) ~[client-intermediary.jar:?] at net.minecraft.class_310.<init>(class_310.java:351) ~[client-intermediary.jar:?] at net.minecraft.client.main.Main.main(Main.java:155) ~[minecraft-1.14.4-client.jar:?] at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:461) ~[fabric-loader-0.14.14.jar:?] ... 10 more Caused by: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered at org.spongepowered.asm.mixin.transformer.MixinProcessor.applyMixins(MixinProcessor.java:392) ~[sponge-mixin-0.11.4+mixin.0.8.5.jar:0.11.4+mixin.0.8.5] at org.spongepowered.asm.mixin.transformer.MixinTransformer.transformClass(MixinTransformer.java:234) ~[sponge-mixin-0.11.4+mixin.0.8.5.jar:0.11.4+mixin.0.8.5] at org.spongepowered.asm.mixin.transformer.MixinTransformer.transformClassBytes(MixinTransformer.java:202) ~[sponge-mixin-0.11.4+mixin.0.8.5.jar:0.11.4+mixin.0.8.5] at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.getPostMixinClassByteArray(KnotClassDelegate.java:422) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.tryLoadClass(KnotClassDelegate.java:323) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassDelegate.loadClass(KnotClassDelegate.java:218) ~[fabric-loader-0.14.14.jar:?] at net.fabricmc.loader.impl.launch.knot.KnotClassLoader.loadClass(KnotClassLoader.java:112) ~[fabric-loader-0.14.14.jar:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:520) ~[?:?] at net.optifine.reflect.Reflector.<clinit>(Reflector.java:197) ~[Optifine-mapped.jar:?] at net.minecraft.class_3268.<clinit>(class_3268.java:82) ~[client-intermediary.jar:?] at net.minecraft.class_1066.<init>(class_1066.java:61) ~[client-intermediary.jar:?] at net.minecraft.class_310.<init>(class_310.java:351) ~[client-intermediary.jar:?] at net.minecraft.client.main.Main.main(Main.java:155) ~[minecraft-1.14.4-client.jar:?] at net.fabricmc.loader.impl.game.minecraft.MinecraftGameProvider.launch(MinecraftGameProvider.java:461) ~[fabric-loader-0.14.14.jar:?] ... 10 more Caused by: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Redirector getCorrectWorld2(Lnet/minecraft/class_310;)Lnet/minecraft/class_638;

It works fine without OptiFabric and Optifine, and if I just use OptiFabric, it says I need to put an Optifine jar in my mods folder. Someone please help!
