I have a code wherein it automates manual processes to transform a 4k row dataset into 38k rows that can be fed into a system.

Main problem: After I finish running the code (takes 6 mins) I experience animation delay (which doesn't happen before running the script). 1 specific example is when I try to apply autofilter. I need to click on cells before the autofilter icon rows on column headers appear. Also when I try to "fit to columns" it takes a few seconds before it gets applied. Sometimes, even clicking on cells are delayed.

Observations:
  1. When I try to open another workbook right after I ran the script, the delay also happens to that workbook
  2. When I try to close the workbook right after I ran the script (without closing the whole Excel app) and then open the same workbook again, it still has the delay
  3. When I try to close the whole Excel app right after I ran the script and save the workbook then open the file again, the delay disappears and the workbook functions normally now
Steps I already took:

Based on one of the recommendations I got, I cleared all the objects declared in my VBA script. It helped a bit but the delay is still there. I tried to watch all the object variables I have and check all of them before ending the main sub to see if they are really cleared. Here's what I got:
I also add the
VBA Code:
Application.CutCopyMode = False
line since I copy a lot of ranges and it helped a bit in terms of the running time but the problem still persists.

Also, I already disabled the graphic acceleration setting in the options menu.

VBA Code:

My code consists of a Main sub calling more subs in different modules. I'll just try to post the main sub and subs from 1 module

MAIN SUB
VBA Code:
Public inputWB As Workbook
Public vbaWB As Workbook
Public laneWS As Worksheet
Public conversionWS As Worksheet
Public basePortWS As Worksheet
Public splitWS As Worksheet

Sub main()
Dim laneLR As Long, parsedLR As Long
Dim startTime As Double, minutesElapsed
Dim rngName As Name

startTime = Timer

With Application
        .ScreenUpdating = False
        .DisplayAlerts = False
        .EnableEvents = False
        .EnableAnimations = False
        .Calculation = xlAutomatic
End With

FileOpenDialogBox
setWB

'copy base port grouping sheet to the vba file
'inputWB.Sheets("Base Port Grouping").Copy After:=vbaWB.Sheets("Conversion")
inputWB.Sheets("Lane Details").Copy After:=vbaWB.Sheets("Conversion")
setWS 'declare ws variables
inputWB.Close
Set inputWB = Nothing

'delete name ranges
On Error Resume Next
For Each rngName In Names
    vbaWB.Names(rngName.Name).Delete
Next
Set rngName = Nothing
On Error GoTo 0

'/*** PHASE 1 - PARSING OF MULTIPLE PORT NAMES ***/'
identifyMultiplePortNames ("F") 'parse origin location rows with multiple port names
transferParsedToLane 'delete filtered rows in lane details with multiple port names
identifyMultiplePortNames ("I") 'parse destination location rows with multiple port names
transferParsedToLane

'/*** PHASE 2 - TRANSPOSING OF NOMINATIONS ***/'
deleteNominationSummary
getLatestBAF
transposeNomination

laneWS.Delete
Set laneWS = Nothing
ph2WS.Rows("4:1048576").ClearFormats

identifyCommodityType

Set ph2WS = Nothing
Set vbaWB = Nothing

'basePortWS.Delete

Application.CutCopyMode = False

With Application
        .ScreenUpdating = True
        .DisplayAlerts = True
        .EnableEvents = True
        .EnableAnimations = True
End With

minutesElapsed = Format((Timer - startTime) / 86400, "hh:mm:ss")

MsgBox "Done! The script took " & minutesElapsed & " minute(s) to complete"

End Sub

LAST MODULE I CALL IN THE MAIN SUB
VBA Code:

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.

It is possible that you are leaking memory when running your macro found that EXCEL can be fairly poor at tidying up variables and releasing memory. So I suggest you look at the amount of memory that excel is using while you are running your macro. See if it the usage goes back to something like it was or is considerably more. If you find it has gobbled up a lot of memory, try putting breakpoints in to find out where you are getting the big jumps. I finally solved my problem by putting a single statement to erase a temporary variant array:
Erase temparr
