I'm working on Windows so I have other reason for this issue. Also all other steam functions working good so it's not about #543

I restructured project (https://github.com/world-of-legends/Alpha_Engine/tree/main/magnum) and now all works. But if someone has same issue just reopen this issue.

If someone will check this issue, I write here code how to embed Sdl2Window into WinForms Control using previous advices: ```cs System.Windows.Forms.Control yourControl; Sdl2Window window = new Sdl2Window(yourControl.Handle); ```
