problem with org-toggle-inline-images

[Johannes Brauer]

Hi!
Typing C-c C-x C-v the image is displayed in the org buffer correctly. Typing 
C-c C-x C-v again the image does not disappear and I get the error message:

org-toggle-inline-images: Symbol’s value as variable is void: image-map

Any hints what is going wrong?

I am using
Aquamacs 3.5  GNU Emacs 25.3.50.1 (x86_64-apple-darwin16.7.0, NS
macOs 10.15.2
Org mode version 9.3 (9.3-8-geab7c4-elpa
