Hey @Burnout.exe! Sorry for the hassle but actually there’s one additional set of logs we need. Could you go to \AppData\Local\UnrealEditorFortnite\Saved\Logs and grab the UnrealEditorFortnite.txt file and send them over here? Thanks! ---

For further reference: this issue _may_ have been tied to internet upload speed. Currently if you have a large project and slower internet the upload process might time out causing you to not be able to cook/launch sessions. I’m not aware of a minimum spec requirement for UEFN but if I find one I’ll post it here.
