DNA file import not working

I created a custom metahuman, and I tried to import the DNA file into UE5, but the DNA file could not be imported. Even if I drag and drop a file, there is no reaction.

‘The Skeleton Face Archetype Skeleton is missing bones that Skeletal Mesh Face_Archetype needs. They will be added now. Please save the Skeleton!’ An error appears.

Even DNA files that were fine before are not imported now.

How can I solve this?

Your DNA file import may not be working due to file format issues, incompatible software versions, or missing dependencies. Make sure the file is formatted right, the software is up-to-date, and all the libraries are installed. The problem might be resolved by updating or reformatting the file.
