It seems that the problem arised since I’ve upgraded orgmode from version 9.2.6 (9.2.6-4-ge30905-elpa to version 9.3 (9.3-8-geab7c4-elpa.
On a system where the older version is installed, toggling works fine.

Hi Johannes,

Thanks for the report.

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?

Possibly variable image-map is not used correctly in Org or should not
be used at all.  The easiest fix would be to drop the usage of that
variable within Org, I guess.

Does the issue disappear when you do

M-: (require 'image) RET

before the image toggling?
no, the behavior remains the same.
