Convai Integration with VRExample - Multiplayer Listen Server

[Omer_Gunyaz]

Hello Convai Team,

I am encountering a critical crashing issue while integrating the Convai plugin into a MR project using Unreal Engine 5.6.1.

The entire Convai workflow, including voice and text chat functionalities, works perfectly fine in Single Player/Standalone mode. However, when I start the game as a Multiplayer Listen Server (LAN), the application consistently crashes a few seconds after the host server is established.

Project and Integration Details

• Engine Version: Unreal Engine 5.6.1

• Convai Version: Latest version from the Marketplace.

• Multiplayer Type: Listen Server (LAN)

• Special Condition: Due to the VR requirements, I cannot change the Player Blueprint’s Parent Class. Therefore, I have manually copied the necessary logic (Chatbot Component setup, Talking/Input Flows, Widget Setup, etc.) from the standard ConvaiBasePlayer into my custom VRPawn Blueprint.

what am i missing?

Thanks

Hello,

Welcome to the Convai Developer Forum!

To help us understand what is going wrong in your multiplayer Listen Server setup, could you please:

1. Confirm the exact Convai plugin version you are using (you can check this in the Convai.uplugin file or the Plugins window).
2. Share the crash logs and callstack from the crash (Saved/Logs folder or the Crash Reporter window).

If possible, also mention whether the crash happens only when a second client joins, or immediately after starting as Listen Server.
