[Python] VS Code cannot automatically activate and switch to the selected virtual Python...

A few days ago, I reinstalled Windows 10, then re-downloaded VS Code and Miniconda3. When I select a virtual environment from the bottom bar in VS Code and run a Python file, the integrated terminal does not start in the selected virtual environment.

Instead, the terminal runs the file using my system-wide Python interpreter, and only afterwards the following two commands appear automatically in the terminal:

PS D:\snow\file\postGra> python -u "d:\snow\file\postGra\test.py"
hello
PS D:\snow\file\postGra> D:/snow/sw/miniconda3/Scripts/activate
PS D:\snow\file\postGra> conda activate base


Additionally, a separate cmd window briefly flashes during execution.

What I have tried:

• 
  Changed the integrated terminal to both cmd.exe and PowerShell — no effect;
  
  
• 
  Reinstalled both VS Code and Miniconda3 — problem persists;
  
  
•

My system:

• 
  OS: Windows 10 Home Edition;
  
  
• 
  Miniconda version: conda 25.5.1;
  
  
• 
  VS Code version: 1.102.2;
  
  
• 
  Electron: 35.6.0;
  
  
• 
  OS Build: Windows_NT x64 10.0.18363.
  

I just want the integrated terminal to activate and use the selected virtual environment automatically when I run a Python file — as it used to before.
