Hi there
Hope you are doing well.
Your only hope is that Acrobat creates a backup copy, which it will do if the option under Preferences (Ctrl,Cmd+K). - Documents - Automatically save document changes... is enabled.
The Autosave feature guards against losing your work in case of a power failure by incrementally, and at regular intervals, saving file changes to a specified location. The original file is not modified. Instead, Acrobat creates an autosave file of changes, which includes all the changes you made to the open file since the last automatic save. The amount of new information that the autosave file contains depends on how frequently Acrobat saves the autosave file. If you set the autosave interval to 15 minutes, you could lose the last 14 minutes of your work if a problem occurs. Frequent automatic saving prevents loss of data, and is especially useful if you make extensive changes to a document, such as by adding comments.
