Hi. I was working on my project a few hours ago and now when I try to open it, it just crashes on start up. The error doesn’t give much info. Could someone help me? I’ve looked through other similar cases but haven’t found a solution. Thanks 
Could you probably also post the log file?
go into your project folder - saved - logs
depending where you have your project, but you’ll find the log in the saved/logs folder
\Unreal Projects\TP_FPS_BP\Saved\Logs
where do i find this?
It’s a text file right? It says I can’t attach it because the file type isn’t valid 
Yep, it should be a text file. Just open up the file and copy everything. Then paste it into a new notepad file.
ok try this goto your maps folder place the Example_Map.umap into a rar/zip file (for safety) then delete it and see if the editor will start up for you
I know this will work, because I already tried it with one of one of the configuration files. I set the default map to something else and it worked. Unfortunately Example_Map is my level with everything in it. I just haven’t renamed it yet lol.
ok have a look here \Saved\Autosaves\Game\Maps to see if any of the backup saves of your map loads
wow…I don’t know why I never thought of this. it should work for sure :). i’m at work but I’ll post whether it does later today.
It didn’t work :(. now what?
not a lot you can do now, if the map is corrupted then afaik its lost.
just start a new map and be more careful don’t forget to save copies more often
well that’s discouraging :(. Thanks for your help though.
Have you already tried to open that mapt with another project? (of course you wont have all the assets in it, but just try it out if you can probably open it, because later you can just move all the assets with the right folder into the new project)
Is there really nothing I can do? Maybe a staff member could look at the log and suggest something else?
Didn’t work. Is it possible that something in the level blueprint is causing it to crash? Can I somehow edit the level blueprint without opening the map?
anything else i can try?
So when you delete that map your are able to open the project? Just to clarify this ^^
Have you already tried to merge the map into another one (it’s used for level streaming)?
and could you probably attach the file so that I can try it out → last thing that comes to my mind
