GDK fails to mirror

I was testing mirroring and it took too long to mirror the repo and started breaking things. It can't even render the repo page now. I updated GDK and it was successful and gdk doctor also says mine is healthy. I've tested mirroring many times, maybe it caused the problem? 🤔

Updated:

It resolved its rendering issue, but I still can't mirror a source project even in master branch.
