Copied hostfxr.dll and put in automationtool and unrealbuildtool folders
Searched google (2days and counting)

yeah i’ve had this problem 5 days now. do you have to verify your UE5 install everytime it happens and have to download 350MB everytime for some reason?

Because I do.

With help i found a solution to package.
Using the Project Launcher which you can find in the top menu under Tool – Project Launcher.
There you can click the + button to create your own profile.
I set the cook and packaging details there and it packages the game perfectly.

“Note that the original bug is still present for me. Meaning i still cant use the platforms – package option.”
I consider that a UE5 bug.

But at least i can package again without any forther issues.
Hope it also works for you.

Im running visual studio 2022
And a clean install of UE5

Thats it

well i’ll be damned. legend it worked. thanks for the info. like you say though, forsure this is not a solution. its a pain but at least there is something to work with now. :slight_smile:

if you do happen to find a real solution be sure to post it, i’ll be sure to do the same vice versa

So i just downloaded UE5.0.1 and i was able to package a project that usually failed by default. I think they may have addressed the issue. unfortunately i cannot find any patch notes about it yet. to see what may have been the problem in the first place.

at this point i have packaged multiple projects with several different build configurations, and they have all gone through for me, it seems they have fixed it, thanks the heavens xD

Sweet! Seems to be fixed for me as well with this update!
Hooray!!
Happy deving
