First Hour tutorial - Migrating level problem

I know that other people have had this GENERAL problem and have asked about this. However, everyone else has seemed to find a solution. When I try to migrate the map from LearningKit, I get the Niagara problem. Uncheck Niagara. Only Game is checked. Fine. But when I go to migrate and it gives the message about assets already existing and click “yes to all”, NOTHING will migrate and it says 0 files were copied and the error log is a whole long list of literally everything. Because clicking “no to all” here and NOTHING is copied. Help.
