OpenGraph/Twitter card broken on main page

Lychee version

6.2.0

Which PHP version are you using?

PHP 8.3

Detailed description of the problem

When linking the main gallery listing on anything using OpenGraph, the image is missing. Work's fine on gallery or individual images. I noticed this is ongoing from v4.

When pulling up the gallery with a verification tool such as https://www.opengraph.xyz you can see that the image is missing.

I have tried on my own install and several other public installs. Seems the variable is undefined at the main landing.

@jmoschetti45 Do you have the welcome mod enabled ?
The default image is the one used by the welcome mod.
You can check with my install: https://photography.viguier.nl

The only thing missing is actually the description.
