VBA Mac Excel 2016：图表.Export权限被拒绝错误70

试图在Mac Excel 2016中将范围另存为jpeg图像。我运行VB代码，首先出现此错误：“运行时错误'-2147287035（80030005）'：指定的尺寸对于当前图表无效类型。” 如果我依次单击“调试”和“ F5”，则会出现以下错误：“运行时错误'70'：权限被拒绝”。

根据我的研究，前者要么是沙盒问题，要么是图表问题。我什至添加了grantAccessToMultipleFiles进行修复，但没有帮助。

有问题的部分：

.Chart.Export Filename:=ThisWorkbook.Path & "/william.jpg", Filtername:="JPG"

这是完整的代码：

Sub SaveImage()
'from stackoverflow originally
Dim sSheetName As String
Dim oRangeToCopy As Range
Dim Lastrow As Integer
Dim manager As String
manager = Worksheets("by Mgr").Range("C6").Value
Set b = Worksheets("by Mgr").Range("T:T").Find(what:="*", SearchOrder:=xlRows, _
    SearchDirection:=xlPrevious, LookIn:=xlValues)
Lastrow = b.Row
sSheetName = "by Mgr" ' worksheet to work on
With Worksheets(sSheetName).Range("A1:T" & Lastrow)
    .CopyPicture xlScreen, xlPicture
    'Getting the Range height
    PicHeight = .Height
    'Getting the Range Width
    PicWidth = .Width
End With
filePermissionCandidates = Array(ThisWorkbook.Path)
fileAccessGranted = GrantAccessToMultipleFiles(filePermissionCandidates)
With Worksheets(sSheetName)
    'Creating the Chart
    .ChartObjects.Add(30, 44, PicWidth, PicHeight).name = manager
    With .ChartObjects(manager)
        'Pasting the Image
        .Chart.Paste
        'Exporting the Chart
        .Chart.Export Filename:=ThisWorkbook.Path & "/william.jpg", Filtername:="JPG"
        End With
    .ChartObjects(manager).Delete

End With
End Sub

我快要结束了，任何想法都值得赞赏。
