1.12.2 version crashes the game (in a modpack) where the original 5zig does not.

The issue provides crash logs via pastebin links. Start by comparing the two logs to identify the specific error or exception causing the crash in version 1.12.2. Look for stack traces pointing to mod initialization or compatibility issues. Determine which Minecraft version and modpack are involved, then test the mod in isolation to reproduce the crash.
