BF6 Campaign Mode Always in Windowed Mode (Can’t Get Fullscreen)

When I launch the campaign mode the game always opens in a windowed mode rather than fullscreen. Even when I go into the Graphics/Display settings and set it to “Fullscreen”, it still behaves like a window. I However, the normal Multiplayer/REDSEC are in fullscreen and function properly.

What I’ve tried so far:

• Changing Display Mode in Settings → Graphics between Fullscreen / Borderless / Windowed.
• Using Alt + Enter.
• Verifying game files / repairing installation.
• Updating GPU drivers and Windows.
