Can confirm this, we got the same error on our team and reverting back to v3.13 fixed it for us for now

I am also experiencing this issue, can confirm reverting to v3.13 makes the issue go away.

Managed to downgrade to v3.13.5 locally by:

1. Add conflict to composer.json:

"conflict": {
    "barryvdh/laravel-debugbar": "=3.14.0"
},

2. Run composer require --dev -W barryvdh/laravel-debugbar

This should downgrade it to v3.13.5 and stop v3.14.0 from being able to be installed in the future. It should not stop updates past v3.14.0 from being installed.

Confirm the same error, in LaravelDebugbar.php on line 908 uses $content[0] without checking existing of this element.

Sorry all, should be fixed with https://github.com/barryvdh/laravel-debugbar/releases/tag/v3.14.1
