Game login problem

I purchased FC 26 through Epic Games and installed it for the first time. When I launch the game, it opens in a small window. At this stage, the game actually loads correctly and I am able to reach the main menu. However, after a few seconds, the game window completely disappears without any error message. Even though the screen disappears, the game continues running in the background. Epic Games and the EA App still show the game as “running,” and it remains active in Task Manager. After this happens, the game does not appear on the taskbar or in the Alt+Tab menu. Additionally, even when I try to end the task from Task Manager, the game often does not close.

I have tried both fullscreen and borderless windowed modes from the in-game settings. Even in borderless mode, the game becomes completely invisible after a few seconds. Windows display scaling is set to 125%, fullscreen optimizations are disabled, and I have verified the game files. I spent more than one hour trying different solutions, but the issue persists and is genuinely frustrating.

I believe this issue may be caused by a software-related problem involving window management, display initialization, or window focus between Epic Games, the EA App, and FC 26. In its current state, the game is unplayable. I kindly request technical support and a permanent solution.

Thank you.
