After updating Computer is only showing Endless screen

I just updated my Acer laptop to 3.4
Now when I restarted, endless logo comes and stayed on

If you updated Endless OS, and now cannot start your computer, we have a solution that will allow you to access Endless OS and all your personal data

I tried multiple time to start and off computer using power button. Now its running ok

Hi @Prashant_Gupta, after 3.4 upgrade we use a new feature to automatically install some apps the first time you boot. This is because LibreOffice has been removed from the core OS and is now installed as a Flatpak. It could make the first boot up in 3.4 take longer than usual, but it shouldn’t take “forever” - you should see increased HDD activity while the installation completes, and then the computer will continue to boot as normal. Of course, if it’s working now, we can’t easily see what the problem was. Can you confirm whether LibreOffice is installed and working OK in your computer, and that you are running version 3.4?
