StarMap crashes when restarting the game via the built in RequiresRestartPopup.Create

[r11b22]

The problem

The game crashes when calling RequiresRestartPopup.Create(null) and pressing Restart Now.

Versions

• StarMap 0.3.1
• KSA v2025.11.8.2847

What could be the problem

The current path is set to the KSA directory but when restarting it restarts StarMap from that directory instead of the StarMap directory

Does this have custom code when running this restart, when reproducing the restart (and also looking at the code), this just seems to shut down the process?

[r11b22]

Yeah maybe i should have supplied the code that i used.

so RequiresRestartPopup.Create(null) is just called when pressing an ImGui button like this

[StarMapAfterGui]
public void guiInit(double dt)
{
    ImGui.Begin("System Reloader");
    if(ImGui.Button("Reload System"))
    {
        Console.WriteLine("Reloading game");
        RequiresRestartPopup.Create(null)
    }
    ImGui.End();
}

From what i can see from a decompiler it runs these lines:

private RequiresRestartPopup(Action? onSuccess)
	: base(onSuccess)
{
	_title = "RequiresRestartPopup".ToProper() + "####" + PopupId;
}

public static RequiresRestartPopup Create(Action? action)
{
	return new RequiresRestartPopup(action);
}
private static readonly PopupButton<Popup> PopupButtonRestart = Popup.CreateButton("Restart Now", delegate(Popup popup)
{
	if (popup is SuccessActionPopup successActionPopup)
	{
		successActionPopup.OnSuccess();
	}
	string fileName = Process.GetCurrentProcess().MainModule.FileName;
	Process.Start(fileName);
	Program.Instance.RequestExit(0);
	popup.Active = false;
});

I hope this answers your question

This could be related https://discord.com/channels/1260011486735241329/1446923707036598454 because the errors shows accesing C:\Program Files\Kitten Space Agency\StarMapConfig.json . Did you put the StarMap files inside the game folder?
