Last version disappeared. Can I recover it?

Last week, we're supposed to upgrade PDM to 2019. So, Friday, every body had to check-in everything. Ok

The upgrade was canceled and no changes were made.

The problem is, when I checked out today a macro I was working on, it says the last version is from feb 8th... One month ago!

But in file properties, it says it was accessed march 8th

Any chance I can recover last week version?
