.fbx not importing mesh

Hello, I am trying to import me mesh into Unreal engine which always worked untill now where it suddenly just imports the materials and not the .fbx


I dont know why all of a sudden it just does not import the mesh only the material in the mesh

When I try to save my scene it shows that I can show the models but I just dont see them in my content browser

Do you maybe have a filter active on your content folder?
