Run Python File: Long delay before command line appears in terminal after terminal window opens

[Jeffrey-deng]

who can help me?

It took a long time to run my code when I pressed the "Run Python File" button. This problem applies to every Python file I try to execute (no matter how long the file is or where the file is in). The time that the terminal is opened and the execution time itself is the same as before, but it takes a few seconds until the one-line command (path of python intepreter) "(path of python file)" appears after the terminal window appears.

When I open VSCode, the speed at which it automatically opens a terminal with the venv activated is normal，But when I manually start a new terminal, it also takes a few seconds before executing the environment activation command, the status bar's "[Activating venv environment]" is spinning.

The version a few months ago was fine.
When I disable terminal.integrated.shellIntegration.enabled, the speed is normal.
