access to geofield_map_setting broken

No evidence of this, that looks just assumption or wrong setup on your side.

The GeofieldMapSettingsForm constructor was created 7 years ago ... (and apparently never changed)
https://git.drupalcode.org/project/geofield_map/-/blame/11.0.x/src/Form/...

Cannot replicate what you report, at all.

Suggestion: clear you drupal cache, if not yet done ... and (if not solved) eventually check what kind of override you are injecting on that Form setup / constructor.

Eventually, reopen and mark this as bug, ONLY if you have clear and objective evidence of the bug you found.
(just assumptions, sorry, are not enough).

I am also encountering the same issue on a fresh Drupal 11 install, locally with DDEV.

Hi, same here, fresh install of Dupal 11.

I wrote a fix for me.

Yes, indeed I could reproduce this issue, after a clean Drupal 11 install, though pretty weird this doesn't happen in my existing Drupal 11 (and 10 site).
I could see that the GeofieldMapSettingsForm is not passing the needed second TypedConfigManagerInterface object to the ConfigFormBase parent object.

Anyway I implemented a better fix (that the classical proposed in patch #4, thanks anyway for that) with this commit:
https://git.drupalcode.org/project/geofield_map/-/commit/969a7eb21104bca...
where the GeofieldMapSettingsForm is refactored to rely on the dependency injection container for adding new services instead of overriding the constructor (@see https://www.drupal.org/node/3076421 → )

New releases of geofield_map ( 11.0.2 → and 3.0.24 → ) are solving all this ...

@itamair Thank you, this is way cleaner :)
