I am trying to enter an application but when I log in to my dashboard it shows me the following error.
Are you using Qlik Sense Desktop or Qlik Sense Enterprise? If the latter, check that the Engine service is running.
I use Qlik Sense Desktop I would believe that the service engine is working because the other apps do let me open them.
Does this still happen if you close Qlik Sense Desktop and restart it?
Just do restart of PC or Qlik Sense.
Right click on the app and select "Open without data". Is the Application worked earlier?
set AppRecoveryMode = 1 in settings.ini file, and try to reopen the app.
