Adobe scan “Send report “ “App closes”

I've been using adobe scan for a month and I really like the app interface and the functionality. Kept uploading hand written notes since a week which had reached 80 pages till date, after scanning today's work, saving file to some time and suddenly the app closed (also called as app crashed). It still closed when i relaunch the app and try to read the same document. Thanks for the feature "save photos" that popped right away after I relaunched the app which still ended up in closing the application.
