After some test, i’ve found that i’m able to run the game when i package it without internet, but if i have it during the packaging, he doesn’t work

Could you please package a sample project and gather the output from the editor. Please obtain one log while the editor is offline and the other log while the editor is online.

Having the exact same problem here… and it’s killing me!!
Packaged a project and cooked it in 4.10.1 and it just won’t launch no matter what. Cooking the same one in 4.9 result in the same problem and as a matter of fact, cooking and packaging just about any project, no matter which, will end up the same.
Three processes appears in task manager, one stuck at 104kb and the other two at 112kb. Stays the same and just can’t even kill them. Ultimately, explorer crashes and even then I can’t kill the processes (nor can I delete the package directory for that matter due to it being in use).
Regrettably, I haven’t cooked anything in a while and it was on a different PC so I’ve no ways of knowing wether it would have worked until recently…

I’ve enclosed the output log and my dxdiag

Solved the issue! Avast was messing with UE4. Now if you too are using it, chances are you suffers from the same problem or it is also related to your own anti-virus acting the same.

Here’s what I’ve done, but remember I’m french so i’m translating my own UI and it might not be exactly accurate:

Open Avast interface
Go into Parameters
In the pop-up menu, go into “active protection”
then into “Files Agent” customisation
In the second pop-up menu, go into “exclusion (or exceptions in english maybe)”
Add the entire unreal editor folder (should be “/program files/epic games/*”) and exclude from writing/reading/execute
Do the same for the folder in which you put your cooked and packaged projects

And voila! It solved it for me. Since I had the exact same issues than you all, chances are high that you suffers the same issue with avast or your own anti-virus

Hey ! I’m using avast too, and i’m pretty sure that he cause the problem ( which why that works without internet ).

Thanks you very much ! Problem solved for me =)

Solved my issue Thank you Alan LJ

(By the way, I’ve previously tried to disable Avast instead of changing the parameters and as it didn’t work (= I didn’t do it correctly), I though the problem was coming from elsewhere :$)

For me it was the game instance that was preventing menus from showing in packaged version. I had moved my custom game instance blueprint to a different folder via the editor. The DefaultEngine.ini still had the old path. Can manually type the path or just in project settings, change the game instance to something else, close, reopen, change it to your instance. Then it rewrites the ini file correctly. But sounds like I will be double checking that file often.
