Audacity crash

Audacity crashed after recording a very long file (8 hours recording) from the radio. I started the recording just after opening Audacity (version 2.0.5), without changing anything in the set up or preferencies.
I was trying to edit the recording in order to extract the requested portion of the file but Audacity crashed and was automatically closed by Windows 10 professional.
Is there any way to recover that file?
I tried to use the Audacity Recovery Utility but it asks for the location of files .au and I could not find any of them.
Can you please help me?

Normally Audacity will recover projects automatically the next time Audacity is launched.

Older versions of Audacity had serious problems in the case of running out of disk space - could that have happened here? These problems have been largely resolved in the current version of Audacity.

The current version of Audacity is 2.2.2 and is available here:
