StuardoRodriguez, thank you for posting the issue.
This should work as expected:

1/ Please try the command Clear /vendor/ cache ... (if it fixes it, we'll focus on this issue)
2/ There might be a generated stub for Illuminate\Database\Eloquent\Builder with missing __construct, by a 3rd-party extension. We should work ok with them, but just to be sure, I guess you've a Laravel extension? (It generates the stubs)
