Adobe just crashed and took all my (saved) work

I edit pdfs in Adobe Acrobat (via comments and sticky notes etc). I have had a lot of problems with the program suddenly closing, sometimes telling me it 'had to close unexpectedly' or it's 'installing updates' - and not saving any of my my comments despite me frequently saving as I work. (And yes, my work is saved in OneDrive so it's on the cloud - but still my changes are automatically deleted whenever it crashes.) I'm losing many hours of work each time this happens. If I had another option I would delete Adobe and try something else. (I have a paid subscription.) Any advice gratefully received! And is there any way I can retrieve the version I was working on? It's not coming up when I click 'Open recent files'.
