Before digging deeper, I’d try stripping the pack down to just Create and Structure Gel to see which one triggers the crash, then add mods back one by one. The error in your log points to something firing during world load, usually a bad mixin or missing dependency.

I’d check for a mismatched mod version in the log, especially Structure Gel or anything Create depends on. Updating both and clearing the config folder usually fixes this kind of crash.
