How to I reconnect megascans after moving my project folder?

Hello, I’ve moved my unreal project to a different directory and drive. The project used Megascans assets and now that I’ve moved them, none of the materials are loading.

A quick investigation into the material instance for that mesh shows the following errors.

What’s the best way to handle this? I don’t want to start messing around to the point of it being irreparable, someone who’s done something similar may know of a process I am supposed to follow. Any guidance is appreciated on this.

What happens, if you right click on the meshes in your content browser and reimport them?
Or check, if the master materials still work properly, and if the instances are still correctly linked to them.
