Can someone help me understand and re-load my newest materials?

Hello everyone,

I had a question about this message that I got in regards to my materials and objects in Unreal Engine, it says that they have failed to load. How can I re-load these materials and objects in my scene?

Not sure if it’s my computer or browser, but the link is not fully loading the screenshot on click. Able to attach it in the post?

Thats an error, something wrong with the assets/references.
