Hello everybody. I faced an error multiple times and I finally tackle it. I decided to publish the solution way to help other users. I hope it will help.
When I try to open my note on the app it gave error that is 'file is corrupted'. Nearly I tried every way I saw but it did not help me. Then I delete the app from Google Play Store and reloading again. Because of I loaded my datas Samsung Cloud BEFORE I delete the app I was able to reload my notes back. And my corrupted note become normal.
