I am done. Please help!

I was editing a video for youtube, and it was done. I just had to add one image and one text filter. I had edited it for about 2 hours and THEN SUDDENLY I DELETE THE TRACK! I press undo and it all looks fine but every filter is gone… WHYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Edit:It all got a lot worse now! I quit shotcut without thinking and don’t save. Then I notice that I could add the text back, but too bad, it’s all gone.
Edit edit:I looked at the autosave folder and it was empty… wut?
