Increased Docker memory size and now docker compose wont work

I increased my docker for windows CPU and memory size in settings, and it did a restart, then I tried to run docker-compose up -d on my project and I got the following error ERROR: Named volume "C:/Users/andersk/sites/sylr:/var/www/html" is used in service "wordpress" but no declaration was found in the volumes section.

Here is my docker compose file, it was working just fine up until I increased those settings in the docker.

version: '3.3'

services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "2000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
     volumes: 
       - C:/Users/andersk/sites/sylr:/var/www/html
volumes:
    db_data: {}

If ran from WSL one can change your docker-compose.yml to the following

version: '3.3'
services:
   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "2000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
     volumes: 
       - /mnt/c/Users/andersk/sites/sylr:/var/www/html

Note the prefix /mnt/c instead of C:/

Another method would be to use a relative path or create a named volume like:

version: '3.3'
services:
   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "2000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
     volumes: 
       - some_volume_name:/var/www/html
volumes: 
   some_volume_name: {}

If ran from Powershell it should work just out of the box.

You can use docker named volume in place and share that name across multiple containers, it would also make debugging easier 

version: "3"

services:
  db:
    image: db
    volumes:
      - data-volume:/var/lib/db
  backup:
    image: backup-service
    volumes:
      - data-volume:/var/lib/backup/data

volumes:
  data-volume:
