   I'm getting this same issue on my VSCode on MacOS. Python virtual environment seems to be active but when running which python it returns python not found.

   Doing the same as this user yields results, and the environment works as expected again.

   By observing the PATH path of this python-debugger plugin, it is obvious that it mistakenly overwrites the original Conda PATH, and the appended path is obviously wrong.

   

   ms-python.python：     
   PATH=C:\Users\sunny\miniconda3\envs\py310;    
   C:\Users\sunny\miniconda3\envs\py310\Library\mingw-w64\bin;    
   C:\Users\sunny\miniconda3\envs\py310\Library\usr\bin;     
   C:\Users\sunny\miniconda3\envs\py310\Library\bin;     
   C:\Users\sunny\miniconda3\envs\py310\Scripts;    
   C:\Users\sunny\miniconda3\envs\py310\bin;      
   .;${env:PATH}   
   

   ms-python.debugpy： 
   `PATH=${env:PATH};c:\Users\sunny\.vscode\extensions\ms-python.debugpy-2025.10.0-win32-x64\bundled\scripts\noConfigScripts`  
   

   ms-python.debugpy：
   PATH= is missing here! ${env:PATH};
   

   You can see that the PATH concatenation of ms-python.debugpy discards the paths such as ms-python.python conda environment, causing Python to fail to execute correctly!

   The python-debugger plugin rudely discards the activated python environment PATH variable and only uses the ${env:PATH}; part.

   Is it #748 that broke it?

   I'm not sure what happened before, but the latest version shows that there is a serious BUG in the environmental contribution.

   José Antunes (@theholy7) Try adding this to your User settings.json and reload:
   Now, you can switch Python environments freely and conda activation works normally.

   尝试将以下内容添加到您的用户 settings.json 并重新加载：
   现在,可以自由切换 python 环境，conda 激活正常。

   settings.json：

   "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"]

   For now I just turned off the debugger. I don't use it. Thank you for the tips though :)
