Problem importing skeleton mesh without textures

I am working on a project and ran into a problem when importing a skeleton mesh into Unreal Editor. The mesh seems to import correctly, but the textures are not applied as they should. I tried checking the import settings and texture paths, but I couldn’t fix the problem and I have no idea if the problem is linked in this.

The following image is the Skeleton mesh component that comes as a static mesh

But if I click on edit skeleton this is how it looks like:

Please help, I have been like this for weeks. I don’t know what the problem is and I don’t understand because 1 year ago I used the same models and I had no problems when importing.
