Fatal error exception after upgrade of statamic/cms to version v3.3.57

[digitalsounds]

Symfony\Component\ErrorHandler\Error\FatalError
Access level to Statamic\Eloquent\Fields\BlueprintRepository::BLINK_FOUND must be protected (as in class Statamic\Fields\BlueprintRepository) or weaker

It looks like the visibility has been changed from protected to private of several constants methods in the class: src/Fields/BlueprintRepository.php from the statamic/cms package and Statamic\Eloquent\Fields\BlueprintRepository extends this class.

This is the commit where the change occurred: https://github.com/statamic/cms/pull/6588/files

In the context of this package its obviously a breaking change, so unsure whether this should actually be raised in the statamic/cms repository instead, happy to move the issue over there if this is the case.
