Line tool useless in V22

I've seen other posts complaining about this, but I wanted to add one. Whatever change was made to the Line tool in this latest version makes it completely useless. I had ONE job to go yesterday, which was to add an arrow to my image. I've done this many times before. But after an hours of trying things, I found no way to succeed in drawing an arrow. After I finished drawing, the arrowhead remains by the line disappears. No changes to stroke width or any other relevant property had any affect. I was able to import an older file which contained an error I'd drawn previously. That came in fine, of course. But I can't make a new one.

I really hope the Line tool returns to its previous, funtional state.
