No, it didn’t get resolved. Actually there is no difference in spark and public/index.php files after copy. I am also using PHP 8.2. There might be something else.
Hello @kapilchugh from a quick research it seems that this is a Codeigniter 4 upgrade issue but I’ve spotted the wrong direction. Please check this post here: Class "Kint\Renderer\Renderer" not found for more.
In short you will need to go to: app/Config/Kint.php and replace Kint\Renderer\Renderer with Kint\Renderer\AbstractRenderer and replace Renderer::SORT_FULL with AbstractRenderer::SORT_FULL
