Error in docker: network "path" declared as external, but could not be found

I am new to docker. I have been assigned with a task that uses Docker container for development. I followed the tutorial for installing the Docker and the containers on Windows 10, but I have the following error: network remaxmdcrm_remaxmd-network declared as external, but could not be found

The steps I've done so far are:

1. Cloned the repository from GitHub.
2. Installed Docker on my laptop.
3. Once I installed Docker, I went in the root of my project and ran the following command. docker-compose build -d -t docker-compose.yml - docker-compose.yml being the file in the root dir.
4. I opened Docker app and I ran the images created.
5. I ran the command docker-compose up. When I ran this command, the error I specified at the beginning appears. network remaxmdcrm_remaxmd-network declared as external, but could not be found

docker-compose.yml

services:
    ui:
        build:
            context: .
            dockerfile: Dockerfile.development
        volumes:
            - .:/app
        ports:
            - "5000:5000"
        restart: unless-stopped
        networks:
            - remaxmdcrm_remaxmd-network

    redis:
        image: 'redis:alpine'
        networks:
            - remaxmdcrm_remaxmd-network
networks:
    remaxmdcrm_remaxmd-network:
        external: true

Ran: docker ps -a

ID              IMAGE
5e6cf997487c   remaxmd-site_ui:latest      
451009e0a2a6   redis:alpine                
85e7cde67d05   docmer-compose.yml:latest 

I might do something wrong here. Can somebody help me? I much appreciate your time!
