QuestTest2.log (258.3 KB)
I am trying to launch a project on Quest 3, but I always get the error PackagingResults: Error: Launch failed! Unknown Cook Failure. I have tried in two separate projects, one is empty and one made with the Unreal VR sample project. I am using Unreal 5.3.1, and I followed the meta quick start guide to make sure I have all the prerequisites. I have attached my log file. Any help on this would be great.
I found the problem. My work security policy was blocking UE from writing to folders in the Program Files directory. I moved my UE5 installation to another folder outside Program Files and that fixed the issue.
