Error commonly occurs when code is incompatible - vba

Question

I wrote a VBA module within an excel document I am working on. I got everything working on my laptop and finally published it to my team to begin a wave of testing.
Unfortunately, a lot of them are met with the following error:
Compile error in hidden module: pushEmail. This error commonly occurs when code is incompatible with the version, platform, or architecture of this application.
At first, I assumed that people were not using the same version of Excel as I was (Excel 2016), however, it turns out that they all were. Other solutions I've attempted are:
Checking the references to ensure that all were included on other user's computers. They were.
Check the add-ins I was using on excel. Besides the default ones, I had none.
Ensure I was using 32/64bit compatible code (as per a recommended solution I found through google). Me and my team all have x64 computers.
I'm not sure what else to try and I have been through the first 30 pages of Google to try and find a solution, to no avail. Could someone suggest a solution that I could attempt?
Thank you in advance.
UPDATE
Here is the code in question:
Sub AcceptPush()
Dim track As Excel.Workbook
Dim push As Excel.Workbook
Dim trackFC As Excel.Workbook
Dim trackWks As Excel.Worksheet
Dim pushWks As Excel.Worksheet
Dim FCWks As Excel.Worksheet
Dim pName As String
Dim TLPass As Variant
Dim lastrow As Long
Dim rngFoundCell As Range
Set rng = Nothing
Dim MyCell As Range
Set push = Workbooks("Push Alert - Software.xlsm")
Set pushWks = push.Worksheets("Push")
Set rngFoundCell = pushWks.Range("R11:R53").Find(What:="y")
pName = pushWks.Range("D2").Value
TLPass = InputBox("Enter the TL Password")
Select Case TLPass
Case "password"
MsgBox "Password correct"
If rngFoundCell Is Nothing Then
MsgBox "You did not select a push to accept."
Else
Set track = Workbooks.Open(ThisWorkbook.Path & "\Account Pushing Tracker - Software.xlsm")
Set trackWks = track.Worksheets("Accounts")
Set trackFC = Workbooks.Open(ThisWorkbook.Path & "\Account Pushing Tracker - Team Tax.xlsm")
Set FCWks = trackFC.Worksheets("Accounts")
pushWks.Range("PushData[#All]").AdvancedFilter _
Action:=xlFilterInPlace, _
CriteriaRange:=push.Worksheets("Filter Criteria").Range("B6:Q7")
pushWks.Range("R:S").EntireColumn.Hidden = True
pushWks.Range("PushData").Copy
trackWks.Range("B" & Rows.Count).End(xlUp).Offset(1).PasteSpecial xlValues
pushWks.Range("PushData").Copy
FCWks.Range("B" & Rows.Count).End(xlUp).Offset(1).PasteSpecial xlValues
pushWks.Range("R:S").EntireColumn.Hidden = False
pushWks.Range("PushData").ClearContents
pushWks.ShowAllData
Range("A1").Select
Application.CutCopyMode = True
track.Close SaveChanges:=True
trackFC.Close SaveChanges:=True
End If
Case Else
MsgBox "INCORRECT! Your attempt has been recorded"
ActiveWorkbook.Worksheets("Log").Unprotect "123"
ActiveWorkbook.Worksheets("Log").Range("A" & Rows.Count).End(xlUp).Offset(1).Value = Application.UserName
ActiveWorkbook.Worksheets("Log").Range("B" & Rows.Count).End(xlUp).Offset(1).Value = Format(Now(), "dd/mm/yyyy hh:mm:ss")
ActiveWorkbook.Worksheets("Log").Protect "123"
End Select
End Sub

Answer 1

When I try to compile your code, it shows you haven't declared the Rng variable:
Set Rng = Nothing

Answer 2

this can occure if 2 Installation of Word/Excel (64 /32 ) or rest of them are on computer.
The apdada....\Excel\STARTUP must be empty too
Maybe try to deinstall all Excel entirely and after new installation try again
