Need help with issue opening potential corrupted cloud file in photoshop

I ran into an issue a week or two ago that I think was triggered by a storage problem.

While I was screen sharing with a client and showing a Photoshop document, an error popped up, something about disk space or storage. Since I was mid-session, I closed the message quickly without reading it properly.

Later that day, I had Photoshop, Premiere, and After Effects all open at once, hopping back and forth. I noticed my storage was almost full, so I started cleaning up space on my PC while those apps were still running, which in hindsight was probably a bad idea and probably caused this issue. During that cleanup, some temporary files were deleted (which I suspect contributed to the problem), and shortly after that, my PC blue-screened.

After restarting my PC, I realized I could no longer open the Photoshop cloud document that had been open during the crash.

Now when I try to open it in Photoshop desktop, I get this error:

“Couldn’t open filename.psdc because the file is not compatible with this version of Photoshop.”

If I try opening it in the web version of Photoshop, it starts loading but then fails with an error.

If I try to download the file (from either the Creative Cloud desktop app or the web interface), the download fails before it starts. I can still make copies of the file from the cloud, but none of those copies open either. I checked the Deleted folder on the web, but there’s nothing there.

It’s only this one cloud document that I can’t open, all my other cloud files seem to work fine. Since this was the one open at the time of the crash, I’m guessing something got corrupted in its sync or whatever.

I assumed cloud documents keep version history, but since I can’t open this one at all, I’m not sure how (or if) I can recover an earlier version.

Any ideas or recovery tips would be hugely appreciated!
