Fullscreen Mode Requires Double Alt+Enter to Work Properly

Issue Description:
Fullscreen mode is not functioning properly on my current system. To achieve proper fullscreen, I need to press Alt+Enter, which initially reduces the game to a small window, and then press Alt+Enter again to enter fullscreen.

It is also important to note that this is the only method to activate AMD Adrenalin driver-level Frame Generation (Fluid Motion Frames), as that feature necessitates fullscreen mode to operate.

System Specifications:
OS: Microsoft Windows 11 Pro Version 10.0.26100 Build 26100  
Motherboard: ASRock Z390 Phantom Gaming 4  
BIOS Version/Date: American Megatrends Inc. P1.00 2018-08-27  
Processor: Intel Core i5-9600K @ 3.70 GHz (6 cores, 6 threads)  
RAM: 32 GB DDR4 (31.9 GB usable)  
GPU: [AMD Radeon RX 6800]  
Secure Boot: Enabled  
Virtualization: Enabled  

Steps to Reproduce:
Launch Battlefield 6 Beta. Select fullscreen in settings. Press Alt+Enter to minimize the game to a small window. Press Alt+Enter again to enter fullscreen.

Expected Result:
Fullscreen mode should function without needing to press Alt+Enter twice.

Actual Result:
Fullscreen mode operates correctly only after performing the Alt+Enter sequence twice.
