I had a similar problem as this, where a crash failed to open recovery options. I was using Animate 2018 on a Mac. I tried to force close Animate again to get into recovery mode but could not get it to offer available recovery files.
I could not find a file with the name Recovery_ anywhere and no back ups of any sort in the same folder as the original. After quite a lot of poking around I recovered a file from just a few days ago when I had last had it opened without any corruption. The files were found in the following directory:
/users/<username>/Library/Application Support/Adobe/Animate CC 2018/en_US/Configuration/TMPxxxxxxxxxx.fla
The xxxx is a alpha numeric system assigned name not recognisable to me and there were 3 files there with different names of the same sort but recognisable as fla files. Two were dated today and corrupted but the third was clean and opened fine. I saved under a new name in my normal directories and I am back where I need to be.
Note Finder does not normally show the Library folder by default but this can be accessed by holding down the alt key and choosing 'Go' on the Finder menu.
It would be great if Animate CC 2018 actually had an option to open available recovery files directly without us all having to look deep into our systems.
Thanks
