UE 5.5.1 crashes when opening a project after plugin deactivation

Hi there,

I’ve been working on a project for couple of days now. In quest for improving overall performance in the editor, I have disabled many plugins (beta or experimental) which i didn’t need.
Now when I try to open the project, UE crashes :astonished:

Is there a way to load the defaults plugins before opening a project?
Is it just me … or UE 5.5.1 seems to be very very buggy and unstable.

thank you

You can right click the .uproject file and open it with a text editor. It should look something similar to this:

{
	"FileVersion": 3,
	"EngineAssociation": "5.4",
	"Category": "",
	"Description": "",
	"Modules": [
		{
			"Name": "ProjectName",
			"Type": "Runtime",
			"LoadingPhase": "Default"
		}
	],
	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": false,
			"TargetAllowList": [
				"Editor"
			]
		},
		....
    ]
}

You can remove the whole “Plugins” section to go back to enabling the Default Plugins. Or you could set “Enabled” to true to re-enable certain plugins.

Just make sure to back up the file before you edit it.

To add onto what Arjun was recommending, you’ll also need to check and see which plugins are required for the project to even run. Some plugins can be missing and the project still functions/opens without them. But, some don’t. I’d enable them back one by one with the method Arjun listed until you find the one that is required for operation.
