It seems this is a system bug https://www.auslogics.com/en/articles/windows-10-update-error-0x8000ffff-fixed/ 

"failed to construct hwtree for collect command," seems also to be related to hardware locality (hwloc) issues that can occur with certain configurations.  Changing the MPI option might resolve this issue.
