Game always go back to Fullscreen when open or restart

Hi guys, bought the Forza Horizon 5 game on Steam on Launch day. Everything works fine except everytime I restart the game or open the game, the game always go back to Fullscreen Mode even though I already saved the Settings in Windowed Mode. Everything saved fine in the Settings except the Fullscreen.
I have my graphic drivers up to dated and everything.
Anyone else having this issue?

Any infos would be appreciated.

No one has this issue?
