Power Query Background Refresh False Error

[wsnyder]

Hi all,

Using Excel 365.

Is my the background refresh false tripping over another background refresh?
I'm getting

Run-time error '1004':
Microsoft Excel is refreshing some data. Please try again later

There are 4 worksheets each with 1 Table created from Power Query Close & Load

 With wb
            For Each ws In .Worksheets
                For Each lo In ws.ListObjects
                    lo.QueryTable.BackgroundQuery = False
                Next lo
            Next ws
        End With

Thanks,
-w
