Cannot remove 'node_modules/': Device or resource busy

I’m trying to set up freeCodeCamp locally on my Windows machine. But I’m running into an error during one of the installation steps.

npm ERR! path /app/curriculum/node_modules
npm ERR! code EBUSY
npm ERR! errno -16
npm ERR! syscall rmdir
npm ERR! EBUSY: resource busy or locked, rmdir '/app/curriculum/node_modules

The node_modules directory under /app/curriculum/ cannot be deleted. And it’s something to do with my setup, because the same command seems to work with another user.

The error happens when I run npm run docker:install, which is defined in their package.json file as "docker-compose run -u root --rm freecodecamp bash patch_npm_and_install.sh".

I tried to get in the container manually and delete the node_modules folder, but even that didn’t work -

PS C:\Users\Manish\Documents\Development\Github\FCC\FreeCodeCamp> docker-compose run -u root --rm freecodecamp bash

rmdir: failed to remove 'node_modules/': Device or resource busy

I tried to use lsof to see if some process is using files in node_modules, but nothing came up -

root@827ef3175784:/app/curriculum# lsof +D /app/curriculum/node_modules
root@827ef3175784:/app/curriculum#

How can I fix this issue?
