Packaged project(server) crashes after player connects

My project works fine in the editor, but my packaged project crashes when a player joins the game.
I have very little to share besides a log that doesn’t show anything … I’ve even disconnected all the client-server logic and the error still occurs.

I’ve changed the pawn in the gamemode, and now multiplayer did work.
I will update when I find out more …

Hey ,

Can you explain anything about the crash you are getting?

  • Is it from the Crash Reporter?
  • Does anything close on its own, such as the server or client windows?
  • Is the connecting player simply not connecting to the server? As in, does the server stay running when the player tries to connect but nothing happens?
  • Is there any sort of notification as to what the error is; such as a popup?

Thanks.

I’ve made an exact bottom up duplicate from my first default pawn class, and found out that the crash was caused by an unused variable (base transform gizmo) which was set to replicated.
