and something(i guess its cmd) crashes while packaging but nothing closes. Its weird. When i click send and restart, it contiunes to packaging.

I deleted everything in my project. EVERYTHING! No meshes, no materials, no blueprints, no structures. There is only GoodSkyShowcaseMap and i cant delete it. When i try to delete it, it crashes with same error in photo above. Now there is nothing in my project except that map but it still CRASHES. Is my project cursed ? I tried packaging in ThirdPersonTemplate and there is still a little Handled Ensure error but it doesnt stop the packaging. It was packaged and i could play. I spended my weeks on that project and i dont have time to make all of them again to any project. I dont know what to do. Unreal Engine is really exhausting. Import something, crashes. Delete something, crashes. Try to play, crashes. Dont do anything, it crashes always.

Im updating: The problem is GoodSkyShowcaseMap. Yes, i didnt open it once, never referenced it in anywhere. But it was the problem. I cant delete it in editor. I cant even right click it. So i deleted it in documentations > unreal projects and it looks fine. The problem is always in the most unexpected place.

In case that this is useful for other people.

Download debug symbol from Epic Launcher. Please see following comment.

How to enable debugging symbols

i want to submit a bug report and i need the call stack for that however when the unreal editor crashes it shows You do not have any debugging symbols required to display the callstack for this crash how do i put debugging symbols this image shows the message i receive from crash reporter [191749-error.png]

Now go to Project Launcher.
We gonna make UE cooker output debug log.

Add your custom profile here.

Add following cooker option.

-ini:Engine:[SystemSettings]:cook.displaymode=2 -verbosecookerwarnings

This command -ini:Engine:[SystemSettings]:cook.displaymode=2 is the same as put following section in DefaultEngine.ini

[SystemSettings]
cook.displaymode=2

Hope this will help other or pinpoint to specific problem.

FYI, I take screenshot from UE4. So, If you use UE5, UI maybe different.
