Answer 1

I also experienced this issue (using Docker Desktop for Windows). For me, I simply issued a restart for Docker by using the following steps:

1. Locate the Docker Desktop Icon (in the Windows Task Bar)
2. Right-Click the Docker Desktop Icon and choose "Restart..."
3. Click the "Restart" button on the confirmation dialog that appears

When Docker Desktop had restarted, I then:

1. Checked for running containers using docker-compose ps
2. Stopped any running containers using docker-compose down
3. Started the containers docker-compose up

And Voila! All containers restarted successfully with no mount errors.

Answer 2

Right click on Docker on Window icon > Setting > Share driver > Reset credentials ... . For me that fix the problems.
