I'm reporting this issue to the official Microsoft VS Code GitHub repository for further investigation.

It seems there is a race condition. See https://github.com/microsoft/vscode/issues/72531

The same issue currently only occurs on Windows 11, and has only been discovered in the last two versions.

VS Code's usability has begun to deteriorate, with randomly slowdowns or even unresponsiveness, especially when multiple instances are running. VS Code seems to be getting slower and slower, and components such as Python LSP are crashing frequently. Reinstalling does not solve these issues.

@Sun-ZhenXing About Python, that likely depends on the extension. Feel free to contribute in their repo: https://github.com/microsoft/vscode-python/issues

Currently, I have found an effective method to reduce the probability of this occurring:

1. Turn off game mode and turn on performance mode on your computer.
2. Turn off energy efficiency mode. You can use code --disable-features=UseEcoQoSForBackgroundProcess to start the application.
