VSTA CREATED DLL

Hello, people
I try to create DLL file with VSTA editor. I have Visual Studio 2019 installed, CorelDraw X5, Windows 10 Home 64 bit

DLL file is ready, but can not start any sub from DLL file

I want to call sub from VBA Module and at top of module I have declarations:

Public Declare Sub FillRectOnDocA Lib "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn2.dll" ()
Public Declare Sub proba1 Lib "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn2.dll" ()
Public Declare Sub proba2 Lib "G:\ONEDRIVE\Documents\Corel\VSTA\CorelDRAW\Addins\AddIn2.dll" ()

Then in same VBA module i have:

Sub just_created_macro()
FillRectOnDocA
End Sub

Sub just_created_macro1()
proba1
End Sub

Sub just_created_macro2()
proba2
End Sub

In Main.vb of Addin2 project code:

<System.AddIn.AddIn("My Add-in", Version:="1.0", Publisher:="", Description:="")> _
Partial Class Main
WithEvents app As Application

Private Sub Main_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
app = CType(Me.Host, Application)

FillRectOnDocA()
End Sub

Public Sub FillRectOnDocA()

Dim rect1 As Shape

app.CreateDocument()

rect1 = app.ActiveLayer.CreateRectangle(1.860965, 8.202012, 6.805957, 3.549126)

rect1.Rectangle.CornerType = cdrCornerType.cdrCornerTypeRound

rect1.Rectangle.RelativeCornerScaling = True

rect1.Fill.ApplyNoFill()

rect1.Fill.UniformColor.CMYKAssign(0, 100, 56, 0)

End Sub
End Class

The code above work well and at start of Corel creates Rectangle

But the other 2 codes don't work

Module Module1
Sub proba1()
MsgBox("OK1")
End Sub
End Module

Public Class Class1
Sub proba2()
MsgBox("OK2")
End Sub
End Class

When I start

Sub just_created_macro()
FillRectOnDocA
End Sub

OR

Sub just_created_macro1()
proba1
End Sub

OR

Sub just_created_macro2()
proba2
End Sub

Run-time error 453 appears

Please help to overcome this problem!

Greetings!
