Cubase became unstable after recording an event, now the WAV files are missing from the Audio folder

I recorded a long event to a single stereo audio track in Cubase 13. I then stopped the recording, saved the project, and closed it. Cubase then popped up a warning saying it had become unstable and to resave under a different name, but by then I’d already closed the project, so there was nothing I could do.

The Audio folder where the WAV file should be stored is empty. If I re-open the project, the “missing files” popup appears.

I understand Cubase writes files to disk in real-time, so how can I recover the data that seems to have been lost?

Thanks for any help or insight.

In case you didn’t see my answer elsewhere - try looking for a .bak file on your hard drive, maybe Cubase saved it a version that was close to complete (I can’t remember if that is turned on by default or not, and what the default autosave interval is).

This was discussed recently on this thread:

No easy answer to this one, unfortunately …
