I can't open my level anymore? if is corrupted can I get an autosave or he's lost forever?

I’m throwing a bottle into the sea because I’m having a big problem with Unreal. I have one of my levels which is “corrupted” I can no longer open it because every time I try it crashes UE, and when I drag and drop the autosaves in content they don’t appear? Am I doing it wrong or is this level lost forever?

Hello @SquidooFR1
Its slightly complicated you have to backup the whole project directory in windows file explorer
C:\Users\Owner\Documents\Unreal Projects\MyPrj53first

Is copied / backed up to
C:\Users\Owner\Documents\Unreal Projects\MyPrj54firstBU
Owner is your username path and “MyPrj53first” is your project name

edit in notepad the MyPrj53first.uproject

{
	"FileVersion": 3,
	"EngineAssociation": "5.3",
	"Category": "",
	"Description": "",
	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true,
			"TargetAllowList": [
				"Editor"
			]
		}
	]
}

In the line “EngineAssociation”: “5.3”,
replace with “EngineAssociation”: “5.1”,
Save this change exit notepad

This will make UE think you need to convert the project to 5.3 and repair the problem
Select Browse and look for the the MyPrj53first.uproject and select and open

When the message appears about creating a new cleaned conversion, click yes to make a new copy

the directory will be the same name but have 5.3 added the “MyPrj53first 5.3”

This will open normally any auto patches have been removed
