Ok, I’ve managed to make it visible adding a lazy loading and a poster image. But even with all other plugins disabled the map is not interactive. The markers has an entrance animation, but i can’t zoom map or move inside it.

If can help in the console the only thing i read is:
Google Maps JavaScript API has been loaded directly without loading=async. This can result in suboptimal performance. For best-practice loading patterns please see https://goo.gle/js-api-loading
