Loop keeps on crashing without an error code

I have a loop that copies a value from a source range and inserts it into a calculator and that triggers a worksheet change event that updates the calculator and a report. The code then copies and pastes the results into a results column. After the result is recorded, it saves the updated report as pdf then goes on to the next item on the source range. After exactly 18 iterations Excel completely crashes and exits the program.

Here is the main macro code:

Sub CalculateEmods()

    Application.ScreenUpdating = False
    Application.EnableEvents = False

    Dim emod As Range
    Dim member As Range
    Dim emodsws As Variant
    Dim i As Integer
    Dim RowCount As Integer
    Dim NeededEmods As Range
    
    Dim FolderName As String
    Dim filename As String
    Dim Folderstring As String
    Dim FilePathName As String
    Dim Report As Variant
    
    Set emodsws = ThisWorkbook.Sheets("2020Emods")
    Set NeededEmods = emodsws.Range("A2", Range("A2").End(xlDown))
    
    FolderName = "EmodFolder"
    RowCount = NeededEmods.Rows.Count - 1

    
    For i = 2 To RowCount
    
        
        Set emod = ThisWorkbook.Sheets("Yearly Breakdown").Range("G334")
        Set member = ThisWorkbook.Sheets("Yearly Breakdown").Range("B2")

        Report = Array("Cover Sheet", "Ag Loss Sensitivity", "Experience Rating Sheet", "Loss Ratio Analysis", "Mod Analysis&Strategy Proposal", "Mod Snapshot", "Mod & Potential Savings")
    
        'Changes member_ID on "Yearly Breaksown" sheet
        Application.EnableEvents = True
            member.Value2 = emodsws.Range("A" & i).Value2
        Application.EnableEvents = False
        
        'Copies emod and pastes it to Emod Worksheet
        emodsws.Cells(i, 4).Value2 = emod.Value2
        
        Set emod = Nothing
        Set member = Nothing
        
        'Prints Emod Report for member as PDF from function
        filename = ThisWorkbook.Sheets("Cover Sheet").Range("B20") & "_Emod" & "_" & ThisWorkbook.Sheets("Yearly Breakdown").Range("F2") & ".pdf"
        Folderstring = CreateFolderinMacOffice2016(NameFolder:=FolderName)
        FilePathName = Folderstring & Application.PathSeparator & filename
        
        ThisWorkbook.Sheets(Report).Select
        
        ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, filename:= _
        FilePathName, Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, IgnorePrintAreas:=False
        
        emodsws.Select
        
        Next i
        
    Application.ScreenUpdating = True
    Application.EnableEvents = True
    
    MsgBox "Emod Reports Created!"
    
    
End Sub

Here is the Worksheet Change Event:

Private Sub Worksheet_Change(ByVal Target As Range)

    
    Application.ScreenUpdating = False
    Application.EnableEvents = False
    
    If Intersect(Target, Range("B2")) Then
    
        Dim primaryarray As Range
        Dim secondaryarray As Range
        Dim rw As Range
        
        Set primaryarray = ThisWorkbook.Sheets("Experience Rating Sheet").Range("B9:M322")
        Set secondaryarray = ThisWorkbook.Sheets("Mod Snapshot").Range("A29:E39")
        
        ' unhide all rows before we begin
        primaryarray.EntireRow.Hidden = False
        secondaryarray.EntireRow.Hidden = False
        
        'function recalculates sheets that wil change number of rows to hide
        Call RecalculateSheets
        
        'hides rows based on criteria set in function
        For Each rw In primaryarray.Rows
            rw.EntireRow.Hidden = BlankOrZero(rw.Cells(3)) And BlankOrZero(rw.Cells(8))
        Next rw
        
        For Each rw In secondaryarray.Rows
            rw.EntireRow.Hidden = BlankOrZero(rw.Cells(1))
        Next
    
        Set primaryarray = Nothing
        Set secondaryarray = Nothing
        
    End If
        
    Application.EnableEvents = True
    Application.ScreenUpdating = True
    
End Sub


Function BlankOrZero(c As Range)
    BlankOrZero = Len(c.Value) = 0 Or c.Value = 0
End Function

Function RecalculateSheets()

    Dim ws As Worksheet
    Dim Report As Variant
    Dim Calculator As Variant
    
    Set Report = ThisWorkbook.Sheets(Array("Cover Sheet", "Ag Loss Sensitivity", _
                                                        "Experience Rating Sheet", "Loss Ratio Analysis", _

                                                        "Mod & Potential Savings"))
                                                        
    Set Calculator = ThisWorkbook.Sheets(Array("Loss Template", "Codes", "Yearly Breakdown"))
    
    Me.Range("B4").Calculate
    
    For Each ws In Calculator
        ws.Calculate
    Next ws
    
    For Each ws In Report
        ws.Calculate
        ws.PageSetup.RightFooter = Sheet17.Range("B3").Text & Chr(10) & "Mod Effective Date:     " & Sheet17.Range("B4")
    Next ws
    
    Set Calculator = Nothing
    Set Report = Nothing
    
End Function

At first I thought it was a flaw in how I wrote the VBA code and initially it would try to use 20 GB of Ram because of the calculations that were happening on a specific sheet. After researching the ram usage problem, I optimized the workbook more got it down to 2GB of Ram usage.

Even though the Ram usage was reduced this dramatically, after 18 iterations it STILL is crashing causing me to think it actually is how I wrote the VBA code.

Here is the last group of lines and the last thread before the crash from the error reporting window that pops up.

Anything I can do to help let me know.

UPDATE:

When I commented out the Save as PDF part of the macro it completes its iterations.

The worksheets that are being saved are pre-formatted and the only thing the loop does is change which rows are hidden and the values within the report selection.

The values and data within the Report change with each iteration so I am looking to capture those in this report with each iteration.

I am thinking this link maybe the direction I need to go but what do you think?
