I lost hours of work!

I lost hours of work!

I was editing in Cubase, doing a post production job, I invested around 6 hours… several times the project was saved as a back up, and when I tried to open them all were damaged… I don’t know if the cause is Spectra Layers One, but definitely something fucked it all up, and it’s not the preferences or the 3dparty plugins… now I have to do it all over again, and I’m thinking of avoiding 100 x 100 Cubase… since it seems it’s not a software where you can work professionally in the post production field, it doesn’t support it…

I already tried to import tracks in a clean project and it doesn’t work… it generates crashdumps, or closes Cubase 11 (last update)

does anyone have any idea how I can recover the work that is encrypted in the cubase file?
