Desperate! Laravel Eloquent ORM relationship not working correctly after recent update, stuck for hours!

hey everyone, really hitting a wall here and could use some urgent help. just launched a new feature for my app, and now my Eloquent ORM relationships are acting super weird. this is really messing up my current Laravel development efforts.

• Context: Recently updated Laravel to 10.x and a few core packages. Everything seemed fine until i tried to fetch related data for a specific user profile.
• The Problem: i have a User model that hasMany Posts. when i try to load a user with their posts using User::with('posts')->find($id), the posts relationship is always empty, even though i can see the posts in the database linked correctly to that user_id. it's like the relationship just isn't being picked up.
• What I've Checked:
  • Model relationships definition in both User.php and Post.php (they seem correct).
  • Database migrations to ensure foreign keys are set up right.
  • Cleared cache (php artisan cache:clear, config:clear, view:clear).
  • Tried direct SQL queries, which return the correct data.
• Urgency: This is a core part of the new feature and it's completely broken. ive been staring at this for hours, trying everything i know. any help would be a major 'laravel quick fix' for me right now.

Any fresh eyes or ideas would be a lifesaver right now. thanks in advance!
