Reproduction steps

1. I try to open a world with mods installed (including Galacticraft and other mods). The world startup completes successfully
2. When I enter the world, I can only see the sky and rain falling. I also hear some strange noise repeated very quickly (as if there was some automatic farm working near the spawn point trying to load). After less than 15 seconds the animations freeze and the game crashes
3. I have a copy of the same world in creative mode, with the same Minecraft version and mods installed and it never crashes
4. I recently increased my PC's RAM from 8GB to 32GB and I allocated 18GB to Minecraft (I thought it didn't have enough memory to load the mods and that specific world) but there was no change in the game

Try with the latest version, if the issue is the same as the provided crash-report, also upload the latest.log file.

I installed Galacticraft 4.0.6 and opened the world again but the game still crashes, with the same error message.
Here's the latest.log file.
Thank you
latest.log

It looks like MusicCraft is causing the crash - try without it.

It works now, thank you so much @marcus8448 and @ROMVoid95 for your help!!
