If your wordpress site isn’t using a theme that is a block template than technically it should be fine from 6.2.1. My sites don’t use block template with its customized theme so none of them are affected with the update.

Wpengine has a good article about a block theme is if you don’t know. https://wpengine.com/builders/block-templates/.

It’s always a good idea to manually update your site’s core wordpress update and plugins. Since you can backup your site first in case something breaks and just rollback to the stable version.
