Missing materials after rename

[ClockworkOcean]

I renamed all the materials in my project and placed them in a newly created folder.
I made sure to run then when I closed the project and re-opened it again I got more than a 1000 error messages saying “Failed to load”

Any ideas on how to fix this?

Did you rename them in the content browser or in outside of Unreal?
