Summary
When Fortnite is set to Windowed Borderless mode, alt-tabbing during the session-loading screen permanently disables all in-game input (keyboard + mouse + controller). The window regains full framerate focus when clicked, but never starts accepting input again.

Steps to Reproduce
Load into any session in Windowed Borderless.
Tab in and out of the game.
Expected Result
Normal input function
Observed Result
Frame-rate behaves as expected: ~30 FPS while unfocused, full FPS when the window is active.
All input is ignored. No menu navigation, movement, or mouse actions register.
Only closing the game from the OS (Alt + F4 or task manager) restores control.
