Try with the below code:

Inject the IContentLoader  dependency on constructor level e.g. private readonly IContentLoader _contentLoader; 

           var contentLinks = block?.ProductContentArea?.FilteredItems?.Select(x => x.ContentLink).ToList();

            if (contentLinks != null && contentLinks.Any())
            {
                var productContentPages = new List<ProductContentPage>();

                foreach (var contentLink in contentLinks)
                {
                    if (_contentLoader.TryGet(contentLink, out ProductContentPage productContentPage))
                    {
                        productContentPages.Add(productContentPage);
                    }
                }                
            }

Hi sanjay,

Thanks for the reply, But could you please elaborate it a little more.
