Hey everyone, i am running into this one error and really could use some help.
i have been trying to package my projects but have failed everytime
what i have tried;
here’s a screenshot of the error
@HDHANAK I know how it feels and I took these steps and my project worked but there was some issues after the packaging was done. May be my experience might help you. Don’t give up and you will figure it out one way or the other.
thank you for your suggestion but disabling these settings makes the problem even worse since i am unable to open my project. It keeps crashing
any other advice or suggestions would be great as it’s urgent
thank you
@HDHANAK unfortunately this is all I have, hopefully someone else can help you. May be @Mind-Brain can help you out. Good luck.
Hey @HDHANAK ! Welcome to the forums.
I would love to try to help you out, but in order to do that I need accuracy of explanation of what is going on. We went from:
“I can’t build. There’s this error”
to
“I can’t open the project.”
Those are two VASTLY different problems. Let’s start by you outlining your biggest hurdle right now. 
thank you for suggesting @GeekManGames
@Mind-Brain the biggest hurdle is packaging the project since i have been trying every single method to package it and nothing has worked
Okay then!
So when you’re packaging, you want to pay attention to the yellow and the red text.
Red text means it WILL NOT proceed, yellow means it will proceed but things could get weird.
When you have red text, you want to follow the lines up until something seems out of the ordinary, based on the error given. Since you don’t really have an error that’s traceable, you’d just go up the line until you see anything saying “This isn’t right”.
So what we need here are build logs.
okay @Mind-Brain i did check for the yellow and red errors and this is what appeared (this is of the blank template of archviz)
hello everyone again sorry for bombarding you all with these msgs but its really urgent any help towards this is appreciated
thank you
So EVERYWHERE I look up both “Crash in runnable thread background worker” and “failed to set completion port for job object “UE.ShaderCompileWorker.JobGroup”: The parameter is incorrect.” What I find is people saying that it’s an issue with their project. My first suggestion would be to run a verification scan of your engine installation through the Epic launcher.
One person said they migrated all the useful assets to a fresh project and then they could cook and package.
Another person said it was because they were using virtual textures, after they got rid of those and deleted the lighting cook data the problem went away.
This is a pretty rare occurrence apparently. You are running on hardware above minimum required specifications, yes?
but the project i am packaging is the blank template of archviz and i have verified and check for errors but didnt found any
yes i am running on hardware above minimum required specifications

Have you run a verification scan through the Epic Launcher? It’s possible that it’s corrupted files.
Also you need to make absolutely sure that your video drivers are up to date.
yes as i mentioned i verified and my drivers are up to date as well
here’s a list of things i have tried:
Have you possibly tried running a ChkDsk command and scanning the files? I had someone recently have issues with building do that and it helped!
no I haven’t
I will try and let you know
Hi Most likely, the issue with building the project could be related to your computer’s specifications being below the recommended requirements. I had a similar problem back in the UE4 days when I simply didn’t have enough RAM during the build process. If possible, check your RAM usage while building the project — if it’s close to maxing out, then that’s probably the cause of the error.
