ERROR: "Unexpected character "/" in variable name near "../utils/config.env"

**Description**
When I try to lunch docker-compose up -d inside the clickstream demo in command prompt

**Environment**
- GitHub branch: [e.g. `6.0.1-post`, etc]
- Operating System: Windows 10 pro
- Version of Docker: 20.10.21
- Version of Docker Compose: v2.13.0

Start by reproducing `docker-compose up -d` from the clickstream demo in Windows Command Prompt with the reported Docker and Compose versions. Inspect the demo's Compose configuration and the referenced `../utils/config.env` path; done means the demo starts without the reported variable-name error, with the affected branch and configuration identified.
