Hi
I ve to pack my project but it give me error, I ve read the log and mainly is error for dlss and landscape.
Starting with the landscap error already in the viewport it say that 1 physical actor have to be rebuild but I rebuild the lendscape data several times and nothing changed, the log(when I start the launcher) say:
The squares are just , anyway it seems to be an error with the highmap and so in cascade it have several other errors.
I don t know minimally how to fix this.
Others errors are related to the dlss plugin but I really don t know how to fix it cause there are some files missing and I don t know why.
Here some logs:

after this there are 2 lines that are identical to the last 2, so I guess the architectural faliure is due to the fact my gpu do not support dlss while the others seems like referring to missing files but I downloaded it as it was said.
If anyone can help is appriciated
I “fixed” the landscape error cause I m with lumen and lendscape is nanite so it wanted vsm activate so the error is no more but it look ugly.
During packing the log is this

I will add that when I do build all or more precise build light the client crash so exept for the huge part of dlss that I have to solve, could be lights the problem?
Checking through both your log extracts, the critical lines are as follows:
Module 'DLSS' (Plugin 'DLSS') references 'XeSSCommon', but 'XeSSCommon' is not available for platform 'WinGDK'
This is the main issue, the DLSS plugin currently installed is not reading “WinGDK” as a valid platform. The engine is looking for a ModuleRules file that the plugin expects, but it is either not present, or mismatched with UE 5.3.
Build lighting is not supported with Lumen enabled
And this is the crash reason, the static light baking is colliding with Lumen, an interaction that is not supported.
So, in order to fix the issue, let’s take the following steps:
First of all, set all your lights to Movable in the Details panel
Then, delete any old lighting data in Content/BuildData
If the lights crash persists, clear out your cached lighting in Saved/LightingBuilds
Next, if you don’t need DLSS, disable it from Edit > Plugins
After that, close UE, go to your project’s main directory, and delete folders Intermediate, Saved, and DerivedDataCache
Allow the project to re-generate files, then test packaging again
On the other hand, if you need DLSS, remove your current plugin, and install the official DLSS plugin bundled with UE 5.3
Whichever path you take, you should also perform a clean install of your NVIDIA drivers, and use the Developer version from the installer
