The listed solutions below are valid, but it would be a better user experience if PBI reported the error or advised user of possible issues rather than just hanging
- Clear PBI Desktop cache: might help.
- Refresh all queries in preview: might help.
- Clean cache then refresh all in preview: might help.
- Disable privacy check for the report: might help
- Check all your path locations under "Data source settings": a broken path can lead to PBI hanging
