Issue on new craft (craftcms3) setups: vendor Twig can't read system variable

After installing craft through composer, setting up the database and running craft setup, I have a craft application ready to go.

When I go to settings/general, I always get a crash with following information:

1. in /vendor/craftcms/cms/src/templates/settings/general/_index.html at line 30
    {{ actionInput('system-settings/save-general-settings') }}
    {{ redirectInput('settings') }}
 
    {{ forms.autosuggestField({
        first: true,
        label: "System Name"|t('app'),
        id: 'name',
        suggestEnvVars: true,
        name: 'name',
        value: system.name
    }) }}
 
    {{ forms.lightswitchField({
        label: "System Status"|t('app'),

        if ($object instanceof DateTime && ($value = self::_dateTimeAttribute($object, $item, $type)) !== false) {

        }
 
        try {
            return twig_get_attribute($env, $source, $object, $item, $arguments, $type, $isDefinedTest, $ignoreStrictCheck);
        } catch (UnknownMethodException $e) {
            // Copy twig_get_attribute()'s BadMethodCallException handling
            if ($ignoreStrictCheck || !$env->isStrictVariables()) {
                return null;
            }
            throw new RuntimeError($e->getMessage(), -1, $source);

The errors on the lines correspond to:

line 30: value: system.name

line 106: return twig_get_attribute($env, $source, $object, $item, $arguments, $type, $isDefinedTest, $ignoreStrictCheck);

line 30: value: system.name

As you can see, all is happening in /vendor, so I guess it must be some setup that I have missed or incorrectly executed. Why is the system variable null? Is it because of my local machine is missing some configuration? (Macbook Pro with macOs Big Sur)

system:
  edition: solo
  live: true
  name: '{YOUR PROJECT NAME HERE}'
