Missing Layers

I was working on a document with a lot of layers and I saved my file, copied and collapsed all layers to a new layer, moved that object around the artboard, and I thought I saved my file again with all the  other layers still there without accidentally deleteing anything. I closed the document and later when I reopened it, all the layers were gone except my layer that I had copied and collapsed all the other layers on to. I did not back up the document to cloud so I can't recover an earlier version of the psd file. Is there a way to recover those lost layers or the previous psd file?
