Magento 2.4.6: All pages 404 after upgrade from 2.3.5-p1

I am getting 404 page not found on all pages including admin dashboard after upgrading Magento from 2.3.5p1 to 2.4.6 on a VPS.

My root .htaccess:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^pub/
RewriteCond %{REQUEST_URI} !^/setup/
RewriteCond %{REQUEST_URI} !^/update/
RewriteCond %{REQUEST_URI} !^/dev/
RewriteRule .* pub/$0 [L]
DirectoryIndex index.php

Pub .htaccess:
