I am getting errors at both php please eloquent:import-entries and just visting any page accessing data from an entry. I have been able to fix this myself by editing Statamic\Eloquent\Fields\BlueprintRepository and changing occurrences private in front of properties and methods to protected.
This is the first error I got:
Access level to Statamic\Eloquent\Fields\BlueprintRepository::BLINK_FOUND must be protected (as in class Statamic\Fields\BlueprintRepository) or weaker
Screenshot of error in console:
