Insert.Pictures returns 1004 error

I have an issue I don't seem able to solve.
I have a code that always worked perfectly. Dynamically could fetch picture-url from a cell and post it in another cell.
Suddenly since 6th this month it returns 1004 error "Unable to get the insert property of the picture class"
Additional strange thing, if I run the macro on a Mac it does work without issues.

Can anybody guide me?

    If PIC_Url <> "" Then
        Set pic = ActiveSheet.Pictures.Insert(PIC_Url)
        With pic
            .ShapeRange.LockAspectRatio = msoFalse
            .Height = ActiveCell.MergeArea.Height
            .Width = ActiveCell.MergeArea.Width
            .Top = ActiveCell.MergeArea.Top
            .Left = ActiveCell.MergeArea.Left
            .Placement = xlMoveAndSize
        End With
    End If
