An abnormal phenomenon appears when you enter the folder where the project is located in Windows 11.

Development environment.

  • Window 11
  • Visual Studio 2022
  • Unreal Engine 5.3.2
  1. I created the project through the Unreal Engine Launcher.
  2. I closed all open programs.
  3. I went into the project folder I created.

A problem has occurred.

No actions can be taken on the folder.
All mouse and keyboard actions do not work.
And after a certain period of time, the folder is turned off and Windows blinks once, making it impossible to run the project.
If the above phenomenon becomes severe, Windows will continue to flicker when you boot the computer.

I would like to ask for help from seniors who know the cause and solution to this phenomenon.

The above article is written in English through Google Translate. Translation may be strange.

This is 99.99% unrelated to Unreal Engine.

No actions can be taken on the folder.
All mouse and keyboard actions do not work.

This is a very peculiar behaviour.

  • best case scenario: antimalware / antivirus is acting up and throws false positives the system is trying to quarantine
  • worst case scenario: hardware failure, faulty RAM corrupting data and writing it back to disk can create bizarre scenarios - have you seen any blue-screens lately?

Open the Task Manager (ctrl+shift+esc) - any processes that seem off during the episodes? Hogging CPU / Memory / Disk?


And after a certain period of time, the folder is turned off and Windows blinks once, making it impossible to run the project.

What does it mean that the folder is turned off? I realise this is a machine translation error - what happens to the folder, it is deleted? Files are missing? How does “impossible to run the project” manifest?
