Administration Joomla! 3.x • Moved to PHP 8 and site stopped working

$

Hello,
I'm planning to move to Joomla 4, and I have -foolishing or wisely! :'( - updated my php from 7. soemtning to 8.2 and my Joomla stopped working.
I don't care about the front-end, it is not working because of the template:
Failed to load 'rt_zenith' template: Please install Gantry 5 Framework!

But I'm worried abotu the backend which displays the following:
version_compare(): Argument #3 ($operator) must be a valid comparison operator
I can't go back to php 7, there is no option for that.

What should I do to solve this? Can I edit comething in the config file or the database to at least h=get my backend work and then go through the old extension removal and upodate process?
