Minecraft 1.12.2 crash (java.lang.NoSuchFieldError: EMPTY)

crash report: https://pastebin.com/7v4AH8e0

I found out that the problem might be the galacticraftcore or the galacticraftplanets (at least when i took of those from the modpack it worked just fine). Is it possible to fix it while using the mods or should i just try older versions?
