The session is correctly restored if an older version (2bcbe6b) is closed and opened in the latest one (67ae9f6), so the problem is with saving session on close.

I apologize for the issue. We're currently hoping to fix this with #16914.

In the meantime you can hotfix it by commenting out these lines:

terminal/src/cascadia/TerminalApp/TerminalTab.cpp

Lines 461 to 470 in 67ae9f6

	if (const auto& settings{ _rootPane->GetContent().try_as<SettingsPaneContent>() })
	{
	ActionAndArgs action;
	action.Action(ShortcutAction::OpenSettings);
	OpenSettingsArgs args{ SettingsTarget::SettingsUI };
	action.Args(args);
	state.args = std::vector{ std::move(action) };
	}
	else

The issue occurs because SettingsPaneContent is not a proper, projected WinRT class (it doesn't have a definition in an .idl file). Due to this, the try_as call fails. try_as calls QueryInterface and without a projection, SettingsPaneContent doesn't get an IID (interface ID). I checked and with cppwinrt there doesn't seem to be any way around defining it in an .idl file.

I've just built from dc4026d (#16914) and session restore works fine.
