options.txt file: Hidden V-sync toggle disabled after upgrade to Windows 11 (FIXED IN WINDOWS UPDATE)

Note: This was fixed in a Windows Update, but the update does not get automatically installed by Windows 11. To install the update, go to Windows Settings > Windows Update > Advanced options > Optional updates and find either "2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353)" or "2022-01 Cumulative Update for Windows 11 for ARM64-based Systems (KB5008353)" and install it. EDIT: This is included in the February security patch for Windows 11

This was discovered while testing MCPE-110006

After upgrading to Windows 11, the hidden V-sync toggle in options.txt does not function and is always disabled, regardless of if the option is set to enabled. This results in higher framerates than expected, and can be a bit of frustration for some who prefer each game to have its own V-sync toggle (although I am not one of them).

Notes:

• This option cannot be toggled in the game options. It can only be changed by modifying the options.txt file.
• This issue has been tested on and does not occur on Windows 10, only Windows 11 has this issue.
• Due to MCPE-110006, it is possible to enable V-sync by putting the game in full-screen.
• If V-sync is enabled on the GPU, the game respects that and enables V-sync, this limiting the framerate.
• It is not believed that this is a hardware-specific issue, as this has been tested on multiple hardware configurations and all were experiencing this issue.
