1. Create the app in a different directory: If you are having trouble creating a React app in the "Documents" directory, you can try creating the app in a different directory that does not require admin privileges.

2. Run the command as an administrator: You can try running the npx create-react-app command as an administrator by using the "Run as administrator" option in the command prompt context menu.

3. Configure permissions: You can try configuring permissions for the "Documents" directory to allow non-admin users to create files and directories.
Hope this helps you resolve the issue!
