Hi @Manaswini_UI

Could you please:

  1. Share a sample workflow where you are encountering this issue

  2. Run the following two commands in the CMD and share their output:

    dotnet --list-runtimes

    dotnet --list-sdks

  3. Details about your Python installation → is it coming from the Python installer or from the Windows store?

It would help us debug the issue a bit better.
