The error occurs in a mixin from smoothswapping, so I would guess it is caused by that mod. Could you check if the issue goes away if you disable that mod?

[slovinsqui]

sure!

[slovinsqui]

yep, that seems to cause the crash, smoothswapping is incompatible

I don't think there's much I can do about it as the error occurs in a mixin from smoothswapping. I'd suggest reporting the issue to them.
