Cannot load scene into memory your document may be damaged

I know this is a coommon error in Adobe Animate, but i really need help with this, this is a project i have been working on for the past year, but recently i was drawing a new asset and then saved the project and colsed Adobe Animate, but when i closed it something weird happend, Adobe Animate closed but it was doing alert thing that apps do on windows (when the app blinks), but Adobe animate was already closed,

Then the next day i was about to continue working on the fla, but when i opened it a little message pupped up saying "Cannot load scene into memory, your document may be damaged " and i already tired everything but nothing works, most of the simobls are stil there, the error just deleted some of them

Here's the file becuase Adobe Animate doesn't let me upload it
