Dedicated Server crash with MetaXRInteraction plugin enabled (UE 5.6) #21
Description
Hello everyone,
I'm encountering a critical issue with the MetaXRInteraction plugin in Unreal Engine 5.6.
My project compiles, packages, and runs successfully on the Client side. However, the Dedicated Server crashes immediately upon startup if the MetaXRInteraction plugin is enabled.
Context:
- Engine Version: Unreal Engine 5.6 (Meta fork)
- OS: Windows 10
Scenario:
- Running a packaged Dedicated Server
Reproduction:
- Using existing project (or creating a new one).
- Enable the MetaXRInteraction plugin.
- Package for Windows (Server target).
- Run the Server executable.
Even if I don't use any assets or classes from the plugin (just having it enabled), the server crashes with an Access Violation error (reading address 0x00000000).
It seems like a Null Pointer Exception. Here is a snippet of the log/callstack:
LogInit: Display: Engine is initialized. Leaving FEngineLoop::Init()
LogLoad: (Engine Initialization) Total time: 0.83 seconds
LogWindows: Error: === Critical error: ===
LogWindows: Error:
LogWindows: Error: Fatal error!
LogWindows: Error:
LogWindows: Error: Unhandled Exception: EXCEPTION_ACCESS_VIOLATION 0x0000000000000000
LogWindows: Error:
LogWindows: Error:
LogExit: Executing StaticShutdownAfterError
LogWindows: FPlatformMisc::RequestExit(1, LaunchWindowsStartup.ExceptionHandler)
LogWindows: FPlatformMisc::RequestExitWithStatus(1, 3, LaunchWindowsStartup.ExceptionHandler)
LogCore: Engine exit requested (reason: Win RequestExit)
It looks like the plugin is trying to initialize VR subsystems or rendering logic on the Server instance, which is headless.
Has anyone faced this issue or knows how to properly exclude the plugin from loading on the Dedicated Server?
Thanks in advance!
