Are you using Telescope? Is this the problem you're experiencing? https://github.com/laravel/telescope/issues/347

I've runned

php artisan clear
php artisan config:clear

Solved for me

For someone still having the issue, it can be solved adding

<server name="TELESCOPE_ENABLED" value="false"/> in phpunit.xml.

Put it together:

<server name="TELESCOPE_ENABLED" value="false"/>
php artisan optimize

I'm not using telescope package, but i've received the same exception on every php artisan call.
I didn't understand what code block crashes.
Over internet there are many resolutions with cache cleaning. Those users received the same message while running phpunit command.
I've tried to run phpunit and received an error related to configuration of one of packages that i've used. So I fixed package config problem and phpunit command runs well. Also, php artisan runs OK for now.
Hope my solution will be useful to someone.

I had the same problem after upgrading with composer update. I had to downgrade. Nothing above worked for me.

Some problem after upgrading from 6 to 7 version

[ProteanCode]

Lumen, upgrading from

• Updating laravel/framework (v8.14.0 => v8.18.1): Downloading (100%)
• Updating laravel/lumen-framework (v8.2.0 => v8.2.1): Downloading (100%)

Happened during seeding
User::factory()->count(200)->create();

Actually a simple
$factory = User::factory();
was enough to make that error

Workaround:

$factory = \Database\Factories\UserFactory::new();
$factory->count(200)->create();
