@sveltejs/adapter-static: copyfile favicon.ico not permitted (npm run build)

Describe the bug I developed an app and it worked with npm run dev. If I try to build it with npm run build, I get the error: EPERM: operation not permitted, copyfile 'C:\Users\Patrick\dev\internal\rust-jungle\static\favicon.ico' -> 'build\favicon.ico'

I also tried running a terminal with admin permissions, but it results in the same error.

Logs Please include browser console and server logs around the time this bug occurred.

To Reproduce Create a new SvelteKit project, use the adapter-static, replace the favicon and try a npm run build.

Expected behavior A clear and concise description of what you expected to happen. build succeeds without any errors.

FYI I had the same issue because:

• I build without a favicon
• I added one and rebuild
• Faced the issue due to the favicon folder

So, I deleted the build folder and then rebuild and now the issue is gone. I added a script anyway to always remove the build folder before a build.

Run npm run preview to preview your production build locally.

Seems that favicon.ico folder isn’t being populated with the default favicon.ico that exists at the root of the static folder. Instead, favicon.ico is placed at the project root (/). Which I would think would be preferred?
