Excel和VBA在宏中中途崩溃

我是VBA新手，希望能对实现用户定义函数有所帮助。我真的很感激任何帮助

上下文：我正在尝试将一批固定宽度的文本文件导入单独的Excel工作簿。文本文件都具有相同的字段和格式。我知道每个字段的长度。目前，我正试图让我的VBA代码为单个文本文件工作

问题：由于我是VBA新手，我查找了现有代码。我发现，并一直试图实现我的TestImport函数（见下文）。（*请注意，…只是为了简洁起见-实际上没有包含在代码中。）

请参阅本文末尾的ImportFixedWidth函数

然后我尝试在工作簿中运行宏，但每次都会导致VBA和Excel崩溃。第一个字段（不是其他字段）导入到打开的工作簿中，但程序停止响应，必须退出

调试：代码编译。在单步执行TestImport或ImportFixedWidth代码时，我没有收到任何错误。我试过在Mac和Windows PC上运行宏（它在两台电脑上都崩溃）。第一个字段在程序崩溃之前被正确导入，所以我不确定问题出在哪里

问题：就调试而言，我不知道接下来的步骤。我的实现中有没有明显的错误？我的下一个逻辑调试步骤是什么

' Compatible with 64-bit platforms.
'
' This function imports text from a fixed field width file.
' FileName is the name of the file to import. StartCell is
' the cell in which the import is to begin. IgnoreBlankLines
' indicates what to do with empty lines in the text file. If
' IgnoreBlankLines is False, an empty row will appear in the
' worksheet. If IgnoreBlankLines is True, no empty row will
' appear in the worksheet. SkipLinesBeginingWith indicates
' what character, if any, at the begining of the line indicates
' that the line should not be imported, such as fpr providing for
' comments within the text file. FieldSpecs indicates how to
' map the data into cells. It is a string of the format:
'           start,length|start,length|start,length...
' where each 'start' is the character position of the field
' in the text line and each 'length' is the length of the field.
' For example, if FieldSpecs is
'           1,8|9,3|12,5
' indicates the first field starting in position 1 for a
' length of 8, the second field starts in position 9 for a
' length of 3, and finally a field beginning in position 12
' for a length of 5. Fields can be in any order and may
' overlap.
' You can specify a number format for the field which will
' be applied to the worksheet cell. This format should not
' be in quotes and should follow the length element. For example,
'       2,8|9,3,@|12,8,dddd dd-mmm-yyyy
' This specifies that no formatting will be applied to column 2,
' the Text (literal) format will be applied to column 9, and
' the format 'dddd dd-mmm-yyyy' will be applied to column 12.
'
' The function calls ImportThisLine, which should return
' True to import the text from the file, or False to skip
' the current line.
' This function returns the number of records imported if
' successful or -1 if an error occurred.
