Userform stopped entering data to the sheet when submitted.

[ibruzzi]

It was working all day. I don't see what I did wrong here, but the submit button does nothing anymore. I have multiple userforms in this sheet, but all of them have the same issue now.
Any help would be very much appreciated.

Option Explicit
Dim sh As Worksheet

Private Sub ComboBox1_Change()
  Dim c As Range, dic As Object
  Set dic = CreateObject("Scripting.Dictionary")
  
  ComboBox2.Clear
  ComboBox3.Clear
  
  For Each c In sh.Range("A2", sh.Range("A" & Rows.Count).End(xlUp))
    If c.Value = ComboBox1.Value Then
      dic(c.Offset(0, 1).Value) = Empty
    End If
  Next
  ComboBox2.List = dic.keys
End Sub

Private Sub ComboBox2_Change()
  Dim c As Range, dic As Object
  ComboBox3.Clear
  
  For Each c In sh.Range("A2", sh.Range("A" & Rows.Count).End(xlUp))
    If c.Value = ComboBox1.Value And c.Offset(0, 1).Value = 

ComboBox2.Value Then
      ComboBox3.AddItem c.Offset(, 2).Value
    End If
  Next
End Sub

Private Sub CommandButton1_Click()
TextBox1.Text = ""
TextBox2.Text = ""
ComboBox1.Value = ""
ComboBox2.Value = ""
ComboBox3.Value = ""
'ComboBox4.Value = ""
End Sub

Private Sub CommandButton2_Click()
Dim x As Long
Dim y As Worksheet

Set y = Sheet18

x = y.Range("A" & Rows.Count).End(xlUp).Row + 1

With y
.Cells(x, 1).Value = ComboBox1.Text
.Cells(x, 2).Value = ComboBox2.Text
.Cells(x, 3).Value = ComboBox3.Text
.Cells(x, 4).Value = ComboBox4.Text

.Cells(x, 5).Value = ComboBox5.Text
.Cells(x, 6).Value = TextBox2.Text
'.Cells(x, 8) = [Text(Now(), "DD-MM-YYYY HH:MM")]



End With

Unload Me
FWI3.Show

End Sub


Private Sub UserForm_Activate()
  Dim c As Range, dic As Object
  Set sh = Sheets("listf")
  Set dic = CreateObject("Scripting.Dictionary")
  For Each c In sh.Range("A2", sh.Range("A" & Rows.Count).End(xlUp))
    dic(c.Value) = Empty
  Next
  ComboBox1.List = dic.keys
  
  With ComboBox4
    .AddItem "1"
    .AddItem "2"
    .AddItem "3"
    .AddItem "4"

With ComboBox5
    .AddItem "4:30"
    .AddItem "4:00"
    .AddItem "3:30"
    .AddItem "2:30"
    .AddItem "2:00"

    .AddItem "1:20"
    .AddItem "1:00"
    .AddItem "0:50"
    .AddItem "0:45"
    .AddItem "0:30"
