Workaround
Note: create a backup of the original report first by downloading or Exporting report definition.

1. In the General Info tab, click on Delete Dataset and test removing each domain used in the report one at a time
2. Then go to Columns tab.  If there is still an error, repeat step 1 and select another domain.  Do this until you identify the problematic domain.
3. Once the Columns tab successfully loads, then delete the dataset domain that is causing the issue.
4. Go back to General Info and click Add Domain. Add back the affected domain.
5. Go to Columns tab.  This is now loading properly.  
6. Re-select needed columns from the domain
