Unable to access to my podcast

I was working on my podcast in Studio when I was suddenly logged out and received the message: “XXX@XXX.com doesn’t have access to this project.” Since then, I can no longer access this podcast—or any of the other podcasts I’ve created previously. I’ve already tried logging out and back in, but the issue persists. Could you please advise me on how to resolve this? I need to deliver the final version of my podcast within the next 1–2 days. 😞
