B4J Question [JDA] Bot crashing on start

[shadowdevfr]

Hi, I was told to create a new thread for this:
When starting the bot, it instantly crashes with this error:

Waiting for debugger to connect...
Program started.

    ... 3 more

second thing, i'm not really sure where to put StartMessageLoop.
Here is my code:

Sub AppStart (Args() As String)
    Dim jda As JDA
    Dim b As JDABuilder
    b.Initialize2("JDA", config.bottoken)
    b.setAutoReconnect(True).setEnableShutdownHook(True)
    b.setToken(config.bottoken)
  
    jda.Initialize("JDA",b.build)
    
    Dim sh As DefaultShardManagerBuilder
    sh.Initialize2("ShardManager", config.bottoken)
    sh.setToken(config.bottoken)
    sh.build
    jda.awaitReady
End Sub

Sub bot_onMessageReceived(event As Object)
    Dim ev As MessageReceivedEvent = event
    Dim msg As Message = ev.Message
    Dim ch As MessageChannel = msg.Channel
    
    Dim msgcontent As String = msg.ContentStripped
    If msgcontent = "!ping" Then
        ch.sendMessage("PONG !")
    End If
    
End Sub

I updated jda with the latest version
