为什么我的 Access 数据库对象变量在读取其模块容器的过程中失去了与其源文件的连接？

如何解决为什么我的 Access 数据库对象变量在读取其模块容器的过程中失去了与其源文件的连接？

我们使用 VBA 工具从 Access 应用程序中提取模块、表单和报告，并为用户创建可执行文件。直到最近，该工具一直运行没有任何问题。但是，当我使用它从几个应用程序中提取时，我不断遇到“自动化错误（远程过程调用失败）”错误。但是，我的同事（在几乎相同的构建中运行相同的代码）能够正常运行。

这是在 Win10 Pro (v2004 - 19041.685)、Office 2016 Pro Plus (16.0.4266.1001) 上运行的。我相信我同事的机器应该是一样的，因为我们刚刚搬到这些笔记本电脑上。

这是核心代码：

Public Sub ExportAll()

    On Error GoTo ErrorProc
    Dim oAccessApp As Access.Application
    Dim odoc As Document
    Dim sFilePath As String
    Dim oDb As Database
    Dim fso As FileSystemObject
    Dim strFile As String
    Dim strFolder As String
    strFile = "accdb path"
    strFolder = oApp.GetFolder(strFile)
    Set oAccessApp = oApp.OpenDatabase(strFile)
    Set oDb = oAccessApp.CurrentDb
    Set fso = New FileSystemObject
    
    If Not fso.FolderExists((strFolder) & "\SCC") Then
        fso.CreateFolder strFolder & "\SCC"
    End If
    
    If Not fso.FolderExists(strFolder & "\SCC\Modules") Then
        fso.CreateFolder strFolder & "\SCC\Modules"
    End If
    
    If Not fso.FolderExists(strFolder & "\SCC\Forms") Then
        fso.CreateFolder strFolder & "\SCC\Forms"
    End If
    
    If Not fso.FolderExists(strFolder & "\SCC\Reports") Then
        fso.CreateFolder strFolder & "\SCC\Reports"
    End If
        
    For Each odoc In oDb.Containers("Modules").Documents
        DoEvents
        sFilePath = strFolder & "\SCC\Modules\" & odoc.Name & ".bas.txt"
        oAccessApp.SaveAsText acModule,odoc.Name,sFilePath
    Next
    
    For Each odoc In oDb.Containers("Forms").Documents
        DoEvents
        sFilePath = strFolder & "\SCC\Forms\" & odoc.Name & ".frm.txt"
        oAccessApp.SaveAsText acForm,sFilePath
    Next
    
    For Each odoc In oDb.Containers("Reports").Documents
        DoEvents
        sFilePath = strFolder & "\SCC\Reports\" & odoc.Name & ".rpt.txt"
        oAccessApp.SaveAsText acReport,sFilePath
    Next
    
    oDb.Close
    Set oDb = nothing
    oAccessApp.Quit
    Set oAccessApp = nothing
    Exit Sub
ErrorProc:
    If Not (oAccessApp Is nothing) Then
        oAccessApp.Quit
    End If
    Set oAccessApp = nothing
    MsgBox Err.Description,vbExclamation,"Error " & Err.Number
End Sub

在提取过程中，被提取的数据库应始终保持打开状态。每个失败都发生在 For Each odoc In oDb.Containers("Modules").Documents 循环中，并且在 odoc 变量引用特定模块时发生。当我逐步通过并到达有问题的模块时，一切都很好，直到遇到 odoc.Name 行，此时数据库关闭并且对象 oDb 的所有消息都显示为“”。

导致问题的模块如下：

Option Compare Database
Option Explicit

我尝试了以下方法：

• 移除问题模块（过程成功完成）
• 重命名模块
• 删除支持编译的条件语句
• 将提取代码移至新数据库
• 从数据库中提取只有问题模块加上带有注释的模块
• 修复微软办公室
• 重新安装 MS Office
• 降级 Windows 更新

有谁知道为什么这可能会失败？任何关于如何纠正的建议将不胜感激。
