How can i get my map back and recover my built data?

So i logged into my project and was about to click my map and it was gone but the built data was still there and when i tried to click the data it says failed to load and when i try to see the problem it just shows a blank message log. Is there anyway anyone knows how i can get my map back?

This is what it looks like when i got on today but yesterday it had my map next to the data and i could enter it.

When you open the editor, the default map is loaded. That’s the reason you see that map.
You can change the default map to open in the editor in the project settings/maps menu.
Probably your map is somewhere in the content paths, you need to look for it. Try using windows, once you know where is you map saved, then you can load it.

Take in consideration thats if you changed the version of the editor, some maps can not be visible. But usually this is when you try to load a map done with a newest version of the editor in an older version. probably not your case.
