Error after upgrading to version 4.1.7

Yes, I also saw that it was fixed in version 4.1.6 following this thread:

https://forum.codeigniter.com/thread-809...#pid392700


The file downloaded and from which I copied the system folder is this:

codeigniter4-CodeIgniter4-v4.1.7-0-g99e0797.zip

PHP Code:

/**
     * The current version of CodeIgniter Framework
     */
    public const CI_VERSION = '4.1.7'; 


And I didn't use composer for codeigniter installation, but manual installation.
