TypeError: Drupal\gin_lb\TwigExtension\GinLbExtension::ginClasses() when adding a block

Hi,

This is called by the Twig function 'glb_classes'.

And it is used a lot in the templates provided by Gin LB.

Could you please specify:
- Gin version
- Gin LB version
- any Layout Builder related modules and their versions
- the fields types and widgets of your block (I suppose it is a block content type and not a custom block plugin?)
- if you can make a dichotomy by changing the Twig templates to remove calls to this function to see which template is triggering the problem.

I suspect something related to 🐛 Multivalued fields throw an error Postponed: needs info . And maybe there is a field type that is provoking problem. Maybe a media library widget or something like that.

Feel free to re-open if the problem is still there with specified steps to reproduce.
