Description

In Laravel 11/12 event listeners can be registered twice when
App\Providers\EventServiceProvider is enabled in bootstrap/providers.php
while the framework also boots its own
Illuminate\Foundation\Support\Providers\EventServiceProvider.

This leads to duplicate listener registrations and side effects
(e.g. verification emails being sent twice).

Steps To Reproduce

In Laravel 11/12 event listeners can be registered twice when
App\Providers\EventServiceProvider is enabled in bootstrap/providers.php
while the framework also boots its own
Illuminate\Foundation\Support\Providers\EventServiceProvider.

This leads to duplicate listener registrations and side effects
(e.g. verification emails being sent twice).

Commenting out
// App\Providers\EventServiceProvider::class
in bootstrap/providers.php
removes the duplicates.

There's no need to add the EventServiceProvider into your bootstrap/providers.php, as events are automatically discovered by default in Laravel 11+, You'd probably more than likely be able to delete it as it's not there by default from 11.x onwards unless you were doing something custom?

If you don't want automatic event discovery, and instead want to keep the provider, I think you can disable it with ->withEvents(discover: false) in your bootstrap/app.php file (added here).

Alternatively, I'd suggest maybe sending a PR to the docs if somewhere wasn't clear?

But it doesn't feel like a framework issue as duplicate events are allowed.
