When a specific skeletal mesh is placed in the map, an error occurs during cooking.

When a specific skeletal mesh is placed in the map and the session is started, an error occurs during cooking.
I have been using the same method as before, but this is the first time I have encountered this error.
Even after checking the output log, I couldn’t identify the cause.
I would like to understand what kind of issue might exist with the asset or skeleton so that I can resolve the error.

Thank you for your help.

I summarized the error points using AI.
I am also attaching them here.
I would appreciate it if you could provide specific suggestions for countermeasures.

By the way, when checking the dependencies of a specific skeletal mesh asset, the following error messages appeared, but I am not sure how to resolve them.
