What is the reason and/or fix for UE5 (5.03 & 5.1) freezing my whole pc?

Oh, if you don’t already see the variables, here is precisely what you need to copy (just below the “Plugins” mention) :

	{
		"Name": "OpenXR",
		"Enabled": false,
		"SupportedTargetPlatforms": [
			"Win64",
			"Linux",
			"Android"
		]
	},
	{
		"Name": "VirtualScouting",
		"Enabled": false,
		"SupportedTargetPlatforms": [
			"Win64",
			"Linux"
		]
	},
