Statamic AppServiceProvider halting app bootstrapping

Throughout the process of upgrading Laravel 10 -> 11, statamic/cms was also upgraded from 4 -> 5. Since this occurred i’ve noticed some service providers not booting when the app is bootstrapping only before calls to Kernel files.

For context, the package ylsideas/feature-flags adds a macro to the Event facade for skipWithoutFeature for use in the kernel schedule which was not loaded at the point of the kernel. Tracing through vendor files led me to the vendor/laravel/framework/src/Illuminate/Foundation/Application::boot method.

When the app is bootstrapping it walks through all service providers and boots them to be accessible. This halts on statamic/cms/src/Providers/AppServiceProvider.php on the line:

$this->app->make(Schedule::class)->job(new HandleEntrySchedule)->everyMinute()

No exception or throwable is thrown from this line, by catching in a try/catch, but additionally no code execution is performed afterwards which causes further service providers to not be booted. This issue does not persist after the kernel is registered and the macro is then applied.

What could this issue be, and how is it possible to debug when no catchable exception is thrown and no logs produced?
