have you taken the repository back up before the upgrade ?

Hi Laks

No back up.

If you have taken backup of the following folders at Windows Server.

%ProgramData%\Qlik\Sense\Apps

before upgrade it will be easy to restore.

Try to duplicate the app in hub or try to do export/import in QMC without loading the data

then try loading the Duplicated app.
