Emergency Laravel Blank Screen Repair

My production Laravel site has suddenly stopped rendering and now shows a blank, white page instead of the usual content. I need someone who can jump in right away, trace the root cause, and restore normal output.

You’ll get SSH and/or cPanel access to the VPS along with the repository (Laravel 9, PHP-FPM 8.1, Composer). I haven’t yet inspected the logs or run an artisan debug, so the first step will be to check storage/logs, the web-server error log, and try php artisan route:list / migrate / config:clear to surface any fatal errors. Once the underlying exception, mis-configuration, or missing package is identified, apply the corrective fix and verify the UI loads correctly on every route.

Deliverables (all must be met before hand-off):
• Application loads without a white screen on every tested page.
• Brief summary of the issue and the exact lines or settings changed.
• Any composer.json or .env modifications committed/pushed so I can reproduce the fix on staging.

I’d like this resolved within the next few hours, so please respond only if you’re confident with Laravel debugging and can start immediately.
