Hi @divcookie121, I see in the backend that you have reached out to the support team, I have escalated internally so they can check directly your file.
For your information, if you're seeing a 404 page when opening a file link, the most common reasons are:
You don't have access to the file
The file has been deleted
In the meantime, here are a few steps you can check:
Make sure you’re logged into the correct Figma account
Check that you’ve accepted the invite to view or edit the file (under the right account)
Check your deleted files in case it was accidentally removed
