This error happens because the object "grass_q" has a Bound to Layout behavior with its property set to 'Hotspot', which is not one of the options (it must be either 'Origin' or 'Edge').
To fix it just choose 'Origin' and save.
I don't think there's anything to fix here - either this is a very old project, or this problem occurred because you previously saved the project with a different language setting, which is not supported.
