Hi!

I am sorry, your scene does not contain any connections or geometry data.
I guess you never deleted history and lost all connections for some reason, I also did not found any primitive creation or edit history.
In this case I would consider your data as lost.
Rebuilding everything from scratch will be faster than reconnecting thousands of nodes without knowing what attributes need to be connected.
I attached something that I recovered, but I can't say if this is helpful, it doesn't look so.
(You can use the "polyCube1" node to resize the input cube in case the scene is helpful)
To prevent data loss like this:
1. Do incremental saves (as often as suitable) and from time to time save or export in an additional format (like FBX or OBJ).
2. Delete history if not needed anymore (on individual or all objects).
3. Create backups.
Also please use proper names and don't use Copy/Paste, use Duplicate instead.
Names like these are really bad.
pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pasted__pCubeShape6
You also have many duplicate names in your scene and some hierarchies have a character count of more than 4000 characters.
If there would be something that could be only manually recovered, than these names would make this really hard or even impossible.
