Installed plugins via Edit window crashing project UE5.3.2

I added the Datasmith plugin to my project to be able to import a .max file to my project. I restarted the engine as instructed, and now I’m getting a crash preventing the file from opening. The plugins are also not appearing in the “installed plugins” in the editor launch menu. I’m completely unable to access my work. Please help!

Hi @SkaldOfTyr .

Go into the project file location

e.g.
cd C:\Users\OWNER\Documents\Unreal Projects\MyProjectName
open the control file. with

notepad MyProjectName.uproject

		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true,
			"TargetAllowList": [
				"Editor"
			]
		},
		{
			"Name": "GPULightmass",
			"Enabled": true
		}
	]

delete the section with comma and the curly brackets

		{
			"Name": "TwinMotion", or something like that
			"Enabled": true
		}

Leaving

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

you have now removed the broken plugin entry.

You MUST have the Twin Motion software installed before activating the Twin Motion Plugins!

You should now be able to open the project without crashing

BTW make a backup of you Unreal Projects directory before making and adjustments to an external usb drive in zip format
