How do I recover my Document after AOO crashes?

[GeaColommbo]

Hallo,
OpenOffice crashed while I was working on document that I had repeatedly saved today and in the past few days. I tried to recover it, but failed and also the original file is missing, how did that happen? It has disappeared from the HD! (or it's not visible anymore?).
Can anybody help me? I'm working on Mac os Catalina...
Thanks!

If you enabled Time Machine (see Apple's documentation), you could retreive a copy.
