UE 4.5 project crashes in MP but not SP

Development Programming & Scripting Multiplayer & Networking

Hi, I’ve been working on a multiplayer project for UE 4. I’ve updated the project from 4.4.3 to 4.5 and now the project crashes whenever I try to play it in multiplayer. If I launch the game with one window it works and if I package the project and play singleplayer it works. When I try to connect (open “localhost”) both client and server crash. If I try to launch the game in “new editor window” with two clients the entire editor crashes.

Here is a pastebin with the crash dump.
I havnt changed anything with how the multiplayer works after updating to 4.5 and it worked in 4.4.3

Thanks in advance

Apparently it’s due to creating a widget on begin play in the player controller. I’ll just not use the UI as the project is made for Oculus and UMG doesnt work with Oculus yet anyway.

Hello CybranM,

I was reading of the issue and want to ask if you could reproduce this issue in the newest version of the engine? If you can I have a few questions I would like to ask to narrow down what is causing the problem.

  1. Can you reproduce this in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue?
  3. Could you provide screen shots of the blueprint(s) that were used to reproduce this issue?
