Audacity crashed

Hey, I have Audacity 2.4.2, and it crashed on me. The file can be opened and it is showing the right duration of the edited recording; however, I see now waveforms and it is playing no sound. Does that mean that everything is forever lost?

Probably yes.

Note that the current version of Audacity is 3.1.3 (available here: Audacity ® | Downloads)
