There is no errors in logs, but the thread is still running when I stop HA.

My guess is that the folder crawler isn't optimized or there is something that makes it loop indefinitely.

I'll do more inspection of this bug latter

Hey there @hunterjm, mind taking a look at this issue as it has been labeled with an integration (media_source) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

After looking at the source code, I guess that the culprit is that recursivity https://github.com/home-assistant/core/blob/3f512e38db9ed3e85626190077134f9274282e2a/homeassistant/components/media_source/local_source.py#L119-L122

            base.children = [
                self._browse_media(source_dir_id, "")
                for source_dir_id in self.hass.config.media_dirs
            ]

If the folder have many files and subdirectories it's will never finish the processing

When we navigate into folders we only need to love the current level and not all subfolder recursively

I do not have enough confidence with HA to rewrite this integration

Is it possible to reopen this issue ?
