Scripts in Gimp 3

I have used Gimp 2.10 until now. The Arrow script (arrows.scm) worked fine. After upgrading to Gimp 3.0.4 the Arrow script does not work any more. I have tried other Arrow script, but none of them worked. How can I make arrows in Gimp 3 ? My OS is Mac OS 15.5 (Sequoia). I am using occasionally Win 11, too. Same problem here!
Any help appreciated!

Is this the arrow script-fu https://programmer97.byethost10.com/Files/arrow.zip

In the zip, two files arrow.scm and arrow_V3.scm for repectively Gimp 2.10 / Gimp 3.0 The arrow _V3.scm can go straight into your Gimp 3 user profile scripts folder. …GIMP/3.0/scripts/ I would check both script version and location.

I use this almost every day kubuntu 24.04 / Gimp 3.0.4 (appimage) but just to make sure this arrow_V3.scm in Win11 / Gimp 3.0.4

Thank You for Your suggestions.
I think, I got arrow.scm from herre: config/gimp/.config/GIMP/2.10/scripts/arrow.scm at master · mid-kid/config · GitHub
arrow_V3.scm dows not work in Gimp 3.0.4.

Well, clearly the correct script does work as demonstrated. The version on your link is for Gimp 2.10 Use the link I provided and get the zip with the two files. There is a very long-standing thread on this script at gimp-forum Arrow Script
