Describe the bug

Using Windows Powershell running this command 'npx create-react-app xx' I get error An unexpected error occurred: "EPERM: operation not permitted, open 'C:\Users\brice\source\repos\xx\yarn.lock'".

Have you tried reproducing this in procmon? This is usually where I start when I run into weird issues like this.
