Java Developer in need of help, winui 3 app runs perfectly using F5, i fail to deploy as a single .exe file

I'm a Java Developer, I know nothing about C# or .NET or WinUI 3. with the help of gpt I managed to create winui 3 application, it is not much at all: 2 labels, 1 input text, 2 buttons and another textbox that shows logs. here is a picture of running using F5:

as you can see it works. now I would like to package it, again with the help of gpt, I ended up with configuration:

packaging using this command line dotnet publish -c Release -r win-x64 --self-contained true and also dotnet publish -c Release -r win-x64 --self-contained true /p:PublishSingleFile=true and the resulting exe file is about 120 MB, which looks like it bundled the runtime needed for it to run without the user needing to install anything (this is a requirement). the problem is that when I open the exe file Nothing happens. at all. Can you PLEASE help me package this application that runs as intended with F5.

I can you give any code or information if required, it's nothing really just the xaml and c# class thing.
