        "name": "Microsoft.NETCore.App",
        "version": "9.0.0-preview.6.24321.8"

        "version": "9.0.0-preview.6.24322.3"
      }
    ],
"configProperties": {
      "System.Runtime.Serialization.EnableUnsafeBinaryFormatterSerialization": true
    }

2. Launching Notatnik Mechanika.exe.
3. Click Dalej button.
4. Input "test01" in password textbox.
5. Input "test01" in Repeat password textbox.
6. Click Dalej button.
7. Input “Appcompat” into Nazwa firmy textbox.

Known Workarounds No.
Tried the following steps:

1. Turn on the AppContext Switch like <EnableUnsafeBinaryFormatterSerialization>true</EnableUnsafeBinaryFormatterSerialization>
2. Install the System.Runtime.Serialization.Formatters nuget package (Failed. Because it is not compatible with this .NET Core 3.0 App. The supported .NET version of System.Runtime.Serialization.Formatters nuget package is .NET 8)

App is using binary formatter in NotatnikMechanika.WinForms.DataMenager.ZapiszDane().

[elachlan]

NotatnikMechanika.WinForms no longer exists in the linked github repo and was removed in commit https://github.com/VersatileSoft/NotatnikMechanika/commit/7751157c3a269366658c5ce9d8c86f618588371c

For the app to work, it needs to add <EnableUnsafeBinaryFormatterSerialization>True</EnableUnsafeBinaryFormatterSerialization>.

Update for the workaround: It works well with the public Nuget package for the application. Closing this issue.
