CreateMap() this._loader.Load is not a function

[ria-stamopoulou]

Angular v.11
angular11-maps v.6.0.11
bingmaps v.2.0.3

While trying to open the map in a modal I am getting the following error:

this._loader.Load is not a function at BingMapService.CreateMap (angular11-maps.js:11143)

HTML:

<x-map #xmap [Options]="_options" [Box]="_box"> <x-map-marker [Latitude]="39.3224047088176" [Longitude]="22.0880781793979"> </x-map-marker> </x-map>

TS:

_options: IMapOptions = { disableBirdseye: false, disableStreetside: false, navigationBarMode: 1, zoom: 6 };
