However, when I change the out of the box class to a functional component and change the code to:

        <FilePicker buttonLabel={'Add Files'}
          includePageLibraries={false}  //hideLinkUploadTab //          hideOrganisationalAssetTab hideRecentTab hideStockImages hideLocalUploadTab
          onSave={_onFilePickerSave}
          context ={context as never}  //Notice the casting!!
 />

It works.

What could be the difference?

Thanks!
