Unreal 5.3 Won't Start

Development Getting Started & Setup

I’m trying to start 5.3, but I keep getting the error stated on the image. This was after I updated Magic Bullet Looks.

The case is likely that Magic Bullet Looks isn’t updated to run on the latest engine version. I suggest disabling it until it’s been updated.

If you want to disable a plugin in Unreal Engine without starting the engine, you simply locate the ProjectName.uproject. It is in the root of your Unreal Engine project folder.

Drag and drop the file into any text editor and something like this should appear:

{
	"FileVersion": 3,
	"EngineAssociation": "5.0",
	"Category": "",
	"Description": "",
	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true
		},
		{
			"Name": "StaticMeshEditorModeling",
			"Enabled": true
		}
	]
}

Simply remove the code plugin lines from the file, save it, and start the engine again.

Have the same issue here since today. Just deleted the Plugin… now it works. Can use the Bullet looks in AE + PR later so its OK

I had the same problem and the plugin wasn’t showing up when I would open the .uproject in Notepad. But! I did follow DuyBaoTram’s suggestion, found the plugin in the engine and deleted it.

This is the way. Just avoided catastrophe by following this after Google wouldn’t give me any relevant search results for my first two hours of trying to solve this.

Where can I find the plugin? It works for previous Unreal versions, so I would love to just disable it for 5.3 until official support comes in a Magiclook update

I had the same thing but no luck editing the project.uproject, (it didn’t have the “Plugins” line in the code.) Also tried DuyBaoTram suggestion, but my files aren’t laid out the same way. (Maybe cause I’m on a mac?)

Finally got it working by uninstalling the latest MagicBullet plugin using the Maxon installer, then re-installing an old version (It gives you that option once you click “install”) I went back to the version I had when I installed UE 5.3, then it worked, but only after restarting my computer.

Hope this helps someone!

Thank you!!! I will try and let you know. I gave up and realize that using 5.2.1 is a work around too until MagicBullet updates.

Which version of MagicBullet did you end up getting to work? I’m in the same boat (macOS, UE 5.3), updated to latest MagicBullet for use in After Effects, and now I can’t launch Unreal Editor. Have tried uninstalling, re-installing, and rebooting with 4-5 different versions already, but still getting some error.
