Hi Rudy Thanks for the reply.
I have migrated and tried a new clean project and its still the same.
Its something to with the menu widget although everything seems fine with the widget. I have tried placing the blueprint widget in world, and spawning it into the world, I have tried almost everything but it still crashes after around 5 matches when returning to the main menu.
The one thing left to try is to trying it again through the editor (as i had a crash yesterday when recording game play in PIE, and see if i can get the output log for it, but it seems to be the widget, as soon as it loads is crashes (after the 5th time returning to menu)
Aside from that it would probably be best to give you screens of the blueprints and widget set up as im 99.9% sure its to do with the main menu widget. Or i can even send you the widget and relevant assets to test on your side. I can`t put up much stuff here publicly, as I am bound to NDAs, but I can e-mail you them, or upload them to drop box etc.
I will try the editor again as suggested and see if i can get the same crash as yesterday with more details. I will post again shortly with more details on that.
This is the last hurdle and i really need this crash fixing, so thanks for your quick reply and I am hoping to get this nailed by weekend
