But i don’t find this folder in main folder of nextcloud. How can i fix this?

Are there nobody to help out?

For the manual upgrade, you normally delete the old code and just keep the data/-folder and the config/-folder. Then you run the updater which should get the code for the apps from the app store automatically. Since the number of files is now limited, you could delete them by hand from your file system, the notification app should be within the apps/-folder.
