Class 'Kint\Kint' not found

To get a base line with CI4, I am trying to get the default 'Welcome_message'  to work on my host provider, HostGator. It works fine on localhost but when I move the files to my hostprovider it gets the 'Whoosh....' error.

I have set the permissions on the write folder and all its subfolders to 777
my .env file set the baseURL as follows:   
      app.baseURL = 'https://ci4.kmplace.net/'

I launch the website from Chrome using:   https://ci4.kmplace.net

It fails and the following is placed in the Log folder

Any ideas?
Thanks in advance

You need to rename Kint, see here: https://forum.codeigniter.com/thread-75621.html
