Hello, While I was editing it happened that the arrows to select parts no longer appear, and only the windows default arrow appears and does not allow me to easily select the parts.
I think the same thing happened to me with the sounds, try also deleting the model and doing it again or else download the place and rewrite it in the place of the original place
It seems like an unknown place setting that disables the hand that selects parts.
I leave this topic open and I hope someone has some answers regarding this.
