You may have autosaves. Your Preferences settings will show you where the path is.
If you have cloud sync turned on, you may have a copy in the cloud. Look in the Cloud desktop.
Are you saying you did not save during the time you were editing? The last version should be there.
This is a known bug from 2017.1.2 all the way to 12.1.1 that happens occasionally when some action triggers the open or save file dialog.
You might want to wipe your premiere settings inside your Documents folder to temporary fix this issue.
You can see the bug in the Taran's feature requests and bug reports for Premiere. Unique ID 508
If you are lucky you might restore most if not all of your work from the latest auto-save.
Same problem happended to me - twice today - "save as" do certainly not function in this version. Only in my case the project didn't freeze, the screen just went to black, and when reopening the project, it was all gone. Auto-save was on, so half of the project saved - the rest ruined.Tried three times - save as ruined the project all three times.
I have never experienced this problem until now with the latest version.
Hello all, I had the SAME issue today while editing a important video that had to be shown at the end of shooting for 8 hours! About an hour into the edit I had made some transitions and moves so I clicked "save as" and the screen went totally black. I could see the windows navigation buttons, (close, minimize,resize). Just as you all have said I opened then file and nothing at all was saved. Thank God for the auto save feature! So for now I just click "save".
I hope that Adobe fixes this issue soon. I am sure that I will accidentally click "Save As" but lets hope I don't! If anyone else finds a resolution, please let us know!
Did this issue happen when you clicked the menus File > Save As, or after you renamed the project file and clicked Save?
Any update on the "Save As" issues? I am still experiencing the issues on both my brand new laptop and my desktop that I updated to Premiere Pro CC 2018.
