Operating system: Windows 10
Java version: 1.8.0 212

Forge version: 33.0.61
Forge mods (if used): Only an empty mod, that i'm trying to write

What do you need help with?

The minecraft client stops while loading, maybe you can find a version mismatch, or have some ideas why this doesnt work.
Im trying to create a custom mod, thats using baritone, but i fail to run with it. Please help. UwU.

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

I use the following package: "API: Only the non-api packages are obfuscated. This should be used in environments where other mods would like to use Baritone's features."

field field_70177_z was not located in the target class net.minecraft.entity.Entity. Using refmap mixins.baritone.refmap.json

You're mixing an obfuscated env and a non-obfuscated one. This isn't a Baritone issue, you should ask in the Minecraft Mod Development Discord or the Forge Discord
