Try running Unreal in Administrator
Try deleting your Intermediate Folder

I just tired both options but still same problem. Packaging failed.

4
5

I have followed those steps as well. Still no luck.

6

When you package does it pop a window up saying you need a SDK or anything like that

7
8

NO. I don’t get that SDK message. i get ERROR: Cook failed. Build failed error .

9

This packing is Window? Android?
I think that it have different solution depending on the Platform.

10

Its for Window.

11

With windows most forums or videos require you to install new DLSS or update

12

i have packaged the another project to days ago succesfully. Now i cant package any project. there is also problem in Build “Building All Levels” its says exporting lighting data %100 done but its running for an hour .

13

Level building depends on how much you have on the level and some times the lighting does take forever because youre supposed to build lighting first then the rest
