cannot import aup3 format. use file>open instead

I’m encountering this error while using the file>open option. I’m compressing the aup3 file and adding it the link to the file here. https://drive.google.com/file/d/1HRhRHqXzoBg2gIe7PsdUMnxARdU-aRLH/view?usp=sharing
It was recorded from an hour long live speaking event. I believe I was able to open the file a few days ago. I am running the most up to date version of Audacity, the same version that the recording was created on. I’d really appreciate any suggestions on how to recover the file or at least the information inside so that I could work on it in some other program if need be. Thank y’all for your time and attention.

Unfortunately it appears that file is totally corrupt.
Opening it in a Hex editor shows that it is filled with zeros (below). There is no data in that file.
