Node no longer available

For one of my OSF projects, which was already linked to a published paper, the link has been broken for a couple of weeks. When I try to access it, it says "The requested node is no longer available." I already tried to contact the support team via email. However, unfortunately, I didnt get any response. The project-link is/was: https://osf.io/ypwuv/. A fix would be lovely.

Thank you!
