Mouse not captured as if game is in background (Windows, Bedrock)

Description: Since the latest Bedrock Edition update, my mouse is no longer captured by the game. The cursor moves freely as if Minecraft were a background window, and camera movement/in-game input via mouse does not work. The mouse works normally everywhere else in Windows.

Steps to reproduce:

1. Launch Minecraft Bedrock Edition (Windows) after the latest update.
2. Load into a world (or stay in the menu).
3. Move the mouse.

Expected result: The mouse is captured by the game and controls the camera/menus normally.

Actual result: The cursor moves like on the desktop, as if the game window did not have focus. Behavior is identical in fullscreen and windowed mode.

Troubleshooting already tried:

• Windowed and fullscreen modes
• Alt+Tab, Esc, clicking the title bar to force focus
• Repair and reset of the app
• Reinstallation
• Closing background apps/overlays
• Updating Windows and drivers
•  

System info:

• OS: Windows 10
• Minecraft version: Latest bedrock
• Mouse model: MSI Vigor VK30
• GPU: Nvidia RTX 3060Ti

Additional notes: The issue started right after the last update; it worked fine before. No other game or application is affected.
