On Laravel 12, Fatal error after installing php-flasher/flasher-laravel — foreach() argument must be of type array|object, bool given

[dlopez525]

Immediately after installing php-flasher/flasher-laravel, the application breaks with the following error:

foreach() argument must be of type array|object, bool given

Simply installing the package causes this fatal error.

Steps to Reproduce:

Create a fresh Laravel app.

Run:

composer require php-flasher/flasher-laravel

Load any page in the app — no usage of flasher() or flasher_render() yet.

Laravel crashes with a foreach() error.
