I had issues with Haunted Harvest on Minecraft before so I decided to test the mod with a fresh install of Minecraft; it crashes on launch on the completely fresh install with no other mods added. I even replicated it on my laptop and it still happens.

i need latest.log. exit code 1 means "the game crashed"

also the issue is in yout post. you have no other mods installed. you need moonlight lib. this cant happen if you install mods with a launcher. dont install mods manually that leads to human errors

That fixes it, you never put anything about moonlight being a dependency on Curseforge.

The crashes don't seem to be coming back but that might be because I allocated more memory to MC.

But it is there. Each file has it marked as a dependency in its dependency section. As I've said if you use a good launcher as you should deps are downloaded automatically
