It maybe caused by loading class net/minecraft/client/renderer/LevelRenderer in the server, I want to try to fix it, but I need learn to code a mod in forge firstly:(

Build it from source (./gradlew build)

You'll probably need a JDK of the right version, there are guides on installing those on the internet
