Linking errors saying the textures dont exist. Did you move anything manually in windows explorer? That will break everything. Sometimes moving stuff in UE4 editor will break everything too.
Did you add the c-media materials package to your project? Is it bought/legit? Does the file referenced exist IE content/textures/resources/T_MacroVariation.uasset?
Try adding it to a fresh blank project, then migrating the files over to your main project. If this works… its your project, if not its the asset package and needs to be re-downloaded.
If that doesnt work try verifiying your engine files and attempting the above, if failure again, complete engine re-install.
Errors like this make me think you moved stuff from users/ade/documents/unreal projects/myproject/content/cmediadadvmats2/data/content/materials/something.uasset somewhere else cause its looking for it in /textures/resources/whateever.uasset which clearly doesnt exist, nor should it
