ESBuild throws errors when copying assets during build [Next8]

[spock123]

Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

Yes

Description

When making a production build of our code, using browser-esbuild, the process throws an error when it comes to copying assets into the dist folder.

The same build works in the old builder.

The involved files and folders do exist, as it also works in the old (current) builder.
Destination is a directory, as it's the folder for our build.

Please provide a link to a minimal reproduction of the bug
