Runtime Error 481 invalid figure when PNG

Gents,

I changed my current code for displaying graphs on my userform

I encounterd at the beginning for each file type gif,jpg and PNG a runtime error 481. But i looked at the code provided in Chart.export creates corrupt files randomly to adjust my code.

Code:

---

Private Sub UpdateChart()
   
    Dim i As Long
   
    For i = 1 To 3
        Sheets("DASHBOARD").ChartObjects(i).Activate
        ActiveChart.Parent.Width = 400
        ActiveChart.Parent.Height = 180
   
    '  Save chart as GIF
        Fname = ThisWorkbook.Path & Application.PathSeparator & i & "_tijdelijk_bestand.png"
        ActiveChart.Export Filename:=Fname, FilterName:="PNG"
        Me.Controls("Image" & i).Picture = LoadPicture(Fname)
    Next
End Sub

---

Now JPEG, and GIF are working fine without error, but i want to use PNG due to transparency and higher quality vs GIF. but as soon i use the PNG it export the firt PNG and after that gives me the 481 error again.

What goes wrong :( ??
