Build Error when using Meta XR Plugin (Version 74.1) with Unreal Engine 5.5.4 - Platform WINDOWS

[XRoseOficial]

Hi everyone,

I’m encountering issues when trying to build my project in Unreal Engine 5.5.4 using Meta XR Plugin Version 74.1 in the default VR Template. The build fails during the process, and after reviewing the logs, it seems there’s an issue related to the plugin integration. BUILD PLATFORM WINDOWS.

Here are the details of the error I’m facing:

Software Versions:

• Unreal Engine: 5.5.4
• Meta XR Plugin: 74.1
• Operating System: Windows 11

Problem Description:

When attempting to package the project for Windows (Win64), the build fails, and the following message appears in the logs: PackagingResults: Error: Unknown Error.

What I’ve Tried:

• Reinstalled the Meta XR Plugin to ensure no installation errors.
• Tried different Build Configuration settings, but the issue persists.

Has anyone else encountered this issue when using Meta XR Plugin with Unreal Engine 5.5.4? If so, how did you resolve it? Any help or suggestions would be greatly appreciated.

Thanks in advance!
