Adobe Animate had an error saving my file, and now I can't open it. (Even the backup file is ruined)

Yesterday, I was working on the assets file for something, but then, the program gave me an error when trying to save the file, and even the backup, and I tried closing and reopening Animate to fix that error, and now there's another problem. I. CAN'T. OPEN. THE. FILE. Not even the "RECOVER" one. I spent a lot of time making that file and I don't want to start over. I tried repairing the file using WinRAR, but it doesn't work. I tried checking the tmp folder, there were no previous versions there. I tried checking "AutoRecoverFilenames.txt", that file is empty. None of the methods I've seen in the forums worked.

Please, restore my broken file to a previous version, or should I say, help me repair it.
