Packaged game crashes on launch

I just successfully packaged my game but when i try to launch it gives me this message: Assertion failed: IsValid() [File:C:\packman-repo\chk\UnrealEngine\5.5.0-Win64\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 1082]
I don’t even have “packman-repo” folder on my C drive and when i paste the path to the explorer it says it can’t find it. I don’t have anything multiplayer related, it’s just a small singleplayer project i started a week ago. I don’t use nanite, lumen or virtual shadowmaps. I use DLSS 4 for reflex and to reduce motion blur from TAA but i carefully followed nvidia documentation when implementing it. The Unreal editor is closed when i open my game. When i was packaging the first time it said that the Visual studio wasn’t up to date so i updated it then it said that it “wasn’t a preferred version” but still finished with no issues.


If i find this file/error in my engine files this is what it is:

No idea what any of it means
Here are my packaging settings:


Project settings for packaging (i haven’t changed anything at all here)

And my plugins:

I hope i can get any help, this project matters a lot for me, thank you in advance

PC:
RTX 3070

I have now completely disabled the DLSS4 plugin!

Now it works! :slightly_smiling_face:

So it’s due to the current version of the DLSS plugin! Shame on NVIDIA! :face_with_symbols_over_mouth:

I have exactly the same problem! - We urgently need a solution!

Unreal 5.5.3
RTX 3080
DLSS4

OK - I found out something else.

If you turn off the DLSS plugin for frame generation, the error/crash doesn’t occur.

By any chance do you have RTX 20 or 30 series gpu? I suspect that it tries to use or initiate framegen and because it physically can’t on anything below RTX 40 it causes the crash. I’m gonna try doing what you said
Edit: Sorry i just noticed your message where you already listed your pc parts, appreciate that

OK what worked for me is enabling “Streamline (deprecated)” plugin
After that worked like a charm
Got the info from the nvidia forum: Unreal Engine 5.5 with StreamlineCore plugin need Streamline plugin? - Gaming and Visualization Technologies / DLSS - NVIDIA Developer Forums

FYI.

They broke the DLSS4 plugin for VR.

DLSS4 causes the right eye to render solid black.

This was not an issue with DLSS3 in UE5.4
