I've tested this with Windows Forms on .NET 8 and 6.
To reproduce, simply create ShellManager using new ShellManager();
It doesn't matter if you assign it to a variable or not, it will always throw the error.
Full stack trace:
ManagedShell.ShellManager.ShellManager()
ManagedShell.AppBar.FullScreenHelper()
