Hey, Celine from the Figma Community Support team here, I hope it's okay that I'm replying in English as I don't speak Chinese! 🙂

Sorry to hear about this, I can imagine how concerning it must be to lose access to your file unexpectedly. I checked internally and can see that a Technical Quality specialist has already reached out to you and is waiting for your response to continue the investigation. Could you please check your inbox as soon as possible and reply directly to your ticket? The sooner they hear back from you, the faster they can help get this resolved. 🙏
