Have you done fresh HLOD build before Launching ?
Can you explain to me how to make fresh HLOD?
A HLOD Build with the latest version of UEFN or just before trying to Launch session
Do a Build Landscape, ignore the yellow warnings with the Show button and see if there are any Red Errors.
Hopefully it points to that external actor thats being referenced as unsaveable.
Have you deleted any custom content ?
Yes, I deleted a custom texture that I no longer needed
Custom content seems to get references stuck in the HLOD, hopefully thats all this is as its referencing cooked content.
The Delete HLODs from the Build menu doesn’t seem to remove these either.
You can try using a totally new HLOD layer, which could help, if its a stuck reference to the deleted custom texture
This is how I replace HLOD Layer (pasted from a text file)
could you send me a tutorial from youtube or video tutorial how to do it? so I can understand better since I have uefn in Italian
I made this list from trial and error, so I don’t know of one.
But I can tell you where it is in the editor if we go through each step and find the bits that aren’t translating too well
where can I find all these functions you described in the editor?
Hey, ich glaube, ich habe das selbe Problem.
Du möchtest deine Map über den Editor starten?
Also “Launch Session” und er lädt es nicht?
Ich habe gerade mal eine neue Map erstellt. Also blank. Die konnte ich starten.
Es scheint also etwas in der Map zu sein, was er nicht hochladen kann und dann ins Timeout läuft.
Versuche jetzt nach und nach Custom Stuff zu löschen und zu gucken, woran es lag.
Wenn du eine Lösung hast, dann gib mir gern mal Bescheid! 
If custom stuff is used and HLODs are built, the custom stuff is used and referenced by the HLOD.
When you delete the custom things from your project, sometimes the reference to that custom thing isn’t deleted from the HLOD file.
And when it tries to launch it can’t find the deleted file.
To fix this I totally delete the HLOD layer and start with a blank one.
But it has to be done in a certain order or it doesn’t work properly.
But this may not be the problem, so doing a Build Landscape will do more than build landscape it will check your map for common problems.
Ok. How can I delete the HLOD Layer?
Does it help, if I copy my Project in a new Map?
I solved the problem, now i can pubblish the map, thank you : )
Check-in Changes using Unreal Revision Control
Using the Content Browser, Add a HLOD Layer from the World menu.
Delete your old HLOD layer and when the window pops up, Replace References to the new one you just made.
On the next window asking to Save content, use DO NOT SAVE
Now the HLOD file is new and empty.
A good time to check it with Build Landscape for Errors (ignore the yellow results)
Double Clicking on your Map Level Thumbnail in the Content Browser will save content, but also reloads the map, which might be just for good luck.
Check-in Changes again
Now try to Build HLODs then try to launch
