Migrating and Upgrading to Joomla! 4.x • Re: Upgrade from 3.10.12 to 4.4.3 (I think) failed, red screen now

The upgrade from Joomla 3 to Joomla 4 failed for three reasons:

1. Session Path Writable is not enabled. Contact your webhost provide to enable it. You were told about this before.
2. Open Base Directive is in effect. Contact your webhost provider to remove the open base directive. You were told about this before.
3. Max. Input Time is undefined; this causes the upgrade to end before finishing. Set Max. Input Time to a value between 60 and 120.

First off, thank you. These items have been remedied via php.ini.
I was then hit with a new issue, and luckily, my host was able to restore the entire site back to a 2/18/24 copy. Once there, I unistalled JCK editor, and attempted to update from 3.10.1 to 3.1.12, and was greeted by this error during the "upload and install" Hybrid option:

ERROR:
