[5.x]: Live preview not working with disabled site

[samuel-clara]

What happened?

Description

When a site is globally disabled in the settings → sites

the live preview function in the CP produces an error when previewing an entry from the disabled site with a twig template that uses

.language(craft.app.language)

full query is {% set entryQuery = craft.entries().site('*').language(craft.app.language).section('section') %}

The error is "Invalid Argument Invalid site: 5"

Steps to reproduce

1. disable a site
2. live preview an entry from this site that uses a entry query with .language(craft.app.language)

Expected behavior

1. previewing an entry of an unpublished site should be possible

Actual behavior

2. not possible to see the preview

I’m not able to reproduce that locally. Please search for that error in your logs (storage/logs) and post the stack trace that follows it.

FWIW, this sounds a lot like what I ran into with #15767.

I also checked this with Ben Croker (issue) from Blitz but as he suggested this seems more likely to be a craft cms related problem. It happens also without using Blitz.
