VBA: Run-Time Automation Error - "Code execution has been interrupted" - vba

Question

I'm attempting to write a program to loop through a directory of excel files and copy a range into a "Master Workbook". When I run the program I am prompted with "Code execution has been interrupted". If I select continue the code will successfully run but then a "run-time error '-2147221080' Automation error" appears.
The line that causes the error is:
Set ws = wb.Worksheets("Project Log")
My question is, why is this line causing the error and or is there a way to bypass the error prompt so that my code will successfully run?
Sub FileCompiler()
Dim folderPath As String
Dim Filename As String
Dim wb As Workbook
Dim Masterwb As Workbook
Dim ws as Worksheet
'set workbook in which data will be copied to
Set Masterwb = ActiveWorkbook
'declare path
'folderPath = "C:MyPath\"
If Right(folderPath, 1) <> "\" Then folderPath = folderPath & "\"
'compile directory data to master spreadsheet
Filename = Dir(folderPath & "*.xls*")
Do While Filename <> ""
Application.ScreenUpdating = False
Set wb = Workbooks.Open(folderPath & Filename)
Set ws = wb.Worksheets("Project Log")
ws.Range(ws.Cells(2, "C"), ws.Cells(2, "C")).Copy
Masterwb.Worksheets("Staging").Range("A" & Rows.Count).End(xlUp).Offset(1, 0).PasteSpecial
ws.Range(ws.Cells(7, "A"), ws.Cells(Rows.Count, "K").End(xlUp)).Copy
Masterwb.Worksheets("Staging").Range("B" & Rows.Count).End(xlUp).Offset(1, 0).PasteSpecial
wb.Close True
Filename = Dir
Loop
Application.ScreenUpdating = True
End Sub

Answer 1

Dim Finfo As String
Dim FilterIndex As Long
Dim Title As String
Dim CopyBook As Workbook
Dim CopySheet As Worksheet
Dim ForecastFileName As Variant
Dim MasterSheet AS Worksheet
Set MasterSheet = ThisWorkbook.Worksheets("Yoursheetname")
'now you can always use master sheet after you set copybook
'Set up file filter
Finfo = "Excel Files (*.xls*),*.xls*"
'Set filter index to Excel Files by default in case more are added
FilterIndex = 1
' set Caption for dialogue box
Title = "Hey there!, select a file"
'get the Forecast Filename
ForecastFileName = Application.GetOpenFilename(Finfo, FilterIndex, Title)
'Change this according to what you need for workbook and worksheet names
Workbooks.Open (ForecastFileName)
Set CopyBook = ActiveWorkbook
Set CopySheet = CopyBook.Worksheets(1)
'Do your code, remember to close
CopyBook.Close savechanges:=False 'Not needed now
You might want to check for the ForecastFileName being False, that is when the users x's out, you will also want to do a little validation the wb sheet is in the right format by checking column headers ect or you will wind up crashing.
