Expected behaviour

when I run python from vscode it gives me an error
& was unexpected at this time.

it seems related to the new way that vscode handle the terminal setting
it is "terminal.integrated.defaultProfile.windows": "Command Prompt"

Actual behaviour

if I switch to "terminal.integrated.shell.windows": "c:\windows\System32\cmd.exe" in vscode settings
it works fine
however vs code mark this setting be deprecated, eventually there will be no way to avoid this issue.

Steps to reproduce:

open vscode, edit settings in json delete "terminal.integrated.shell.windows" if any
then use vscode menu to select "Termnal:Select Default Termnal" to select "command prompt" (git bash, or power have same issue)
Then run any python file.
Conda activate works, but then second line to call python pops above error.

Same issue with Git Bash as I'm using it everywhere - bash: syntax error near unexpected token `&'.

terminal.integrated.defaultProfile.windows uses the default activation command for PowerShell. The only workaround I'm using is also terminal.integrated.shell.windows.

This is occurring since VSCode 1.56 I believe where default terminal profiles were added.
