FIXED !

After many days of research, countless attempts, I compared one functional project to the buggy startup project, and finally identified two parameters to change in order to permanently eliminate this issue!

To do this,

  1. Create your project, and once it’s open, close it.

  2. Navigate to the project folder and open the “.uproject” file in a text editor.

  3. There will be two initial parameters to set to false instead of true below the Plugins line :

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

  4. Save it and reopen your project in Unreal, and for me, there were no more issues!

Here is my uproject file if needed to copy exact same strings :
Initiation.uproject (2.1 KB)
