Important Draft file suddenly disappeared and is not in Trash

Hello!
An extremely important Figma Design file suddenly disappeared from my account.
I am the original creator and owner of the file. It was stored in my Drafts. I did not intentionally delete it, move it, or transfer ownership.
I have already checked:
• Drafts
• Recents
• Search
• Deleted files / Trash
• Other available teams/workspaces
The file is nowhere to be found, including Trash.
I still have the original link:
https://www.figma.com/design/vDKFLKI73xQZUSQ8IfyxjB/111?node-id=921-278&t=hrXBSwEpux2yFgaB-4
File key: vDKFLKI73xQZUSQ8IfyxjB
Last known file name: 111
When I open the original link now, Figma says that the file is unavailable / does not exist.
This file contains a large amount of very important work, so losing it would be critical.
Has anyone experienced a Draft disappearing completely without appearing in Trash? Is there any way to determine what happened to this specific file or recover it?
If a Figma team member sees this, I would really appreciate it if you could check the status of this file or advise me on the fastest way to have it investigated.
Thank you!
