The YAML file contains two references to a file.
m_DstState: {fileID: 110283043}
&
m_DstState: {fileID: 110232664}

If you’re not using the standard assets imported from an earlier version of unity you can delete the file or delete the references and it will build. Not sure if there’ll be issues with the 2dCharacterAnimator.controller. (I’d assume there is.)
