Every time you make structural changes Power BI Desktop throws away all meta data and recollects it. Set your RangeStart and RangeEnd to two adjacent dates,  then let Power Query do its thing and do not interfere. Messing with it will make it worse.

I did the same. There is no merging, sorting or anything. Set RangeStart and RangeEnd to one day only, and again when loading into desktop it just keep loading and spinning. 
other tables work just fine.

      The table is connected to 6 other child tables. After removing one of the child tables in Power Query, the data loaded into PBI Desktop quickly this time. I also checked the database for constraints and indexes, and everything seems to be in good order. Could an incorrect relationship in the PBI data model have caused the issue?

        If you refresh an incremental refresh partition all of its dependencies will be refreshed as well. That is especially devastating when you have Auto Date/Time enabled.
