There is an active bug with Google search. It’s not loading the profile images in the local knowledge panel section. If you search for your favorite business and the local knowledge panel shows up in the search results, both desktop or mobile results, the profile images will not load. Instead, you will either see a blank white space or a broken graphic image.
This is a global and widespread issue that has been reported to Google. We assume it will be resolved shortly, but until then, you do not need to panic. Google should fix the issue on its end.
Here are some screen shots I took from both desktop and mobile of some local knowledge panels:
