New Blender version 4.5.7 works. Many settings are not present, but just set what you can, with help below, some pointers.
Use a plain axis empty. If you choose the wrong one you will never ever be able to see it.
The video is not clear, but it is important to have a texture file that has contrast. Just a new texture file as spoken in the video does nothing, because it is either completely black or white. Your grass will not move. You can use the leaf texture (edit: correction: cone picture) that the course has supplied. That one is a drawn leaves image. Just click to choose and load that one.
