How To FIX .fla Animate Project file corruption PLEASE!

So I have a little story.

Ok, so I was  working on an Animation in Adobe Animate, and I had like 50% of the project completed but then something happened.

I was working on the file as usual but when I tried to save it, it said "Unable to save file....", I started to panic and left it open for a whilehoping the autosave would fix it(it did not). Then I checked my project folder and saw that there was a recovery file in there, so I calmeddown and just closed the file. But when I tried to open it again it said "An error occured while opening file <filename>". I tried EVERYTHING. Tried to use the Recovery file, did not work. Tried using a program called "DiskDrill" to try and fix the corruptedd file, did not work, and I tried every single suggestion I could find and none of em worked. So ONE MONTH of work, GONE!!!!!, btw I had multiple recovery files and all of em gave me the same dam error.

SO I just gave up and took some time off, after 2 days I decided to restart, after working for 2 more days IT GOT CORRUPTED AGAIN!!!!!

I have no idea why prety sure its not the hard drive cause the only files which got currupted are the animate files I have premiere pro as well and those files are fine among other files.

Tried to look for different ways to fix it(incase I missed something) but still nothing. I am sick and tired of this cause it seams like the only program suffering is animate, so much for a "professional" program.

Can some one please help me fix this(if its possible), and I would love to hear how I can prevent this from happening again.

Please I need help
