Blender with Anaconda environment error on Blender:Start

[Failxxx]

I recently installed Blender 3.0. I have chosen to use an anaconda environment in order to install python packages which would then be available in Blender. I have correctly linked the python folder of my anaconda env here: C:\Program Files\Blender Foundation\Blender 3.0\3.0. If I launch blender from the anaconda prompt, everything is working fine.
However, when I use the Blender:Start command in VSCode, I have the following error message:

Read prefs: C:\Users\felix\AppData\Roaming\Blender Foundation\Blender\3.0\config\userpref.blend
Unable to find the python binary, the multiprocessing module may not be functional!

Terminal will be reused by tasks, press any key to close it.

The second line of the message (Unable to find the python binary, the multiprocessing module may not be functional!) is strange because it does not appear when I launch Blender through the anaconda prompt. I think the issue could come from here, so I tried to set up some environment variables in the Path (in my Windows parameters) variable, but it does not do anything.
Has anyone already faced this issue?

logic for finding python was changed relatively revently. Try newest blender.
Otherwise I recommend this nice lecture: https://projects.blender.org/blender/blender/src/branch/main/source/blender/python/intern/bpy_interface.cc#L438

[Mateusz-Grzelinski]

oh, wait, this error is on our part. This is very weird scenario, our logic might not handle it well. Try

1. newest extension from store
2. extension from master branch

Otherwise I need from you to tell me how do I find python interpreter path when using anaconda & blender. Usually one of those work:

getattr(bpy.app, "binary_path_python")
sys.executable
bpy.app.binary_path
