Additional Info:

I was playing it earlier in the day and it worked fine. I closed it and tried adding some mods and this happened. I have since disabled those mods and it continues to crash. I have tried updating Java to no success and I have plenty of RAM(16gb). I have seen others with this issue but so far nothing has worked.

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from AsmodeusCore (asmodeuscore)
Caused by: java.lang.NoClassDefFoundError: micdoodle8/mods/galacticraft/api/galaxies/CelestialBody

This mod is causing a crash.

Also, assigning that much RAM is not recommended. You're assigning 18 GB which is way too much. 8 GB is more than enough.

@Heufneutje Thank you for your help I disabled it and it launched fine. Could allocating that much RAM cause an issue, I had seen others that had this error and claimed that increasing RAM helped so I put it at something that I knew would be enough. It didn't help but I figured i'd leave it anyway unless it causes problems. Again thank you for your help

Increasing RAM does indeed help but increasing it too much can cause significant lag spikes due to the way Java works.

Good to know. Thank you once again for your help.
