HeavenlyFLARE

Hi! I'm not sure if 1.12 forge is still allowed to be posted here so please don't ban me. So My Forge 1.12.2 server won't start and shows long error code. I try to run my server from the .bat but it just shows this error. I tried 2 different servers (both the same forge version) on one pc and then only tried one on another. Thanks in advance for any help!

my modded minecraft crashed right as it was finishing stage 1 5/5 entity loader one but i only saw this in the crash report: "java.lang.NoClassDefFoundError: net/minecraftforge/client/model/pipeline/VertexLighterFlat" and "java.lang.NoClassDefFoundError: net/minecraftforge/client/model/pipeline/VertexLighterFlat". thanks in advance for any help!
