Problem happened to me before with the same package. It was isolated to my laptop, same code, different laptop worked. Delete all build files doesn't work. Reinstalling ROS doesn't work. System doomed. Launch camera first individual and then launch node after. Trying a lot helps too.
Need to write to ROS discourse, about this.
