Java Card Eclipse Plug-in: APDU I/O API is hanging on powerUp()

Question

My development environment:

1. I downloaded an example for APDU I/O API: https://github.com/RimGazzeh/JavaCard_Wallet.git
2. Eclipse IDE for Java Developers (includes Incubating components) Version: 2023-09 (4.29.0) Build id: 20230907-1323 OS: Windows 10, v.10.0, x86_64 / win32 Java vendor: Eclipse Adoptium Java runtime version: 17.0.8.1+1 Java version: 17.0.8.1
3. Java Card Development Kit Simulator 3.1.0
4. Java Card Development Kit Tools 3.1.0

This is the issue that I have:

If I check "Do not open APDU console" then I get the error message

Exception in thread "main" 0xffffff82 at com.sun.javacard.apduio.ClientT1Protocol.exchangeApdu(ClientT1Protocol.java:55) at com.sun.javacard.apduio.CadT1Client.exchangeApdu(CadT1Client.java:33) at monpackageclient.MyClient.Select(MyClient.java:61) at monpackageclient.RunClient.main(RunClient.java:17)

If I uncheck "Do not open APDU console" then the Client is hanging on powerUp().

I started in both scenarios the Eclipse Simulator manually. But in the second scenario I also run the scripts: cap-monpackage.script (I commented the line //powerdown; out) and afterwards the script create-monpackage.monpackage.MyServer.script.
