Changing screen settings crashes the game (SOLVED)

[Asatte32]

Hi, I am working on a main menu and there is vsync and fullscreen toggle options on it. There are 2 problems that currently ends the game session:
1: If I toggle on and off fullscreen, the game seems to be closed but is actually a background process. I need to end it from the task manager before I can run another instance of the game
2: If I toggle on or off the VSync option when screen mode is changed (set fullscreen on), the game crashes. I assume it is because the previous update on screen settings change is not applied properly.

VSync toggle on/off:
var graphics = (Game as Game).GraphicsDeviceManager; graphics.SynchronizeWithVerticalRetrace = true; graphics.ApplyChanges();

Fullscreen toggle on/off:
var graphics = (Game as Game).GraphicsDeviceManager; graphics.IsFullScreen = false; graphics.ApplyChanges();

Error thrown after vsync enabled with fullscreen state changed:

Could you try changing the fullscreen with Game.Window.Fullscreen and not using graphics.ApplyChanges? I'm not sure what the equivalent for vsync would be, but the graphics manager is probably not the right place to change these things

Thank you, using Game.Window.Fullscreen solved the issue.
Fullscreen: Game.Window.Fullscreen = true/false
VSync (enabled): GraphicsDevice.Presenter.PresentInterval = Stride.Graphics.PresentInterval.One;
VSync (disabled): GraphicsDevice.Presenter.PresentInterval = Stride.Graphics.PresentInterval.Immediate;
