Problem/Motivation
Gin Layout Builder is throwing this WSOD error message after an upgrade from 1.0.0-beta16 to 1.0.0-rc6, affecting the entire website, even pages using the frontend theme:
The website encountered an unexpected error. Please try again later.

Steps to reproduce
- Drupal
9.5.11
- Gin LB version
1.0.0-rc6
Proposed resolution
Gin sometimes gets an empty argument for the $language variable. We should probably make the code more flexible to accept a null language variable.
