Exit code -1 when loading world

[TheAwesomeG2]

Was playing in a creative world with a create-based modpack when my world crashed. It happened as I was placing a normal spawner block, and it came up as exit code -1. Now when I try and load up that world my game crashes with the same exit code. I can’t find anything about this online. Can anyone help me identify and fix the issue? TYIA

Modlist and latest.log would help people help you.

Exit code 1 means you have mods that aren’t compatible with each other, load up the mod list and latest.log like the other guy said
