URGENT: Dynamic XML Sitemap Generation for Laravel SEO Suddenly Breaking After Update, Need Help!

hey everyone, i'm completely stuck and kinda desperate right now. i've been pulling my hair out for hours trying to fix this sitemap issue on my main Laravel project, and i'm hitting a wall.

the problem: dynamic xml sitemap is completely hosed!

• i have this dynamic xml sitemap generation feature for my Laravel app, which is super critical for our Laravel SEO efforts. it was working perfectly fine until i pushed a new update this morning.
• now, when i try to access the sitemap.xml, i either get a blank page, a 500 error, or a malformed XML document that google search console is rejecting outright. it's like the entire generation process just died.
• the goal is an auto-updating, future-proof sitemap, but right now it's just... broken.

what i've tried so far (and failed):

• checked logs: the laravel.log is surprisingly quiet, no obvious errors pointing to the sitemap generation itself, just some unrelated warnings.
• cleared cache: ran php artisan cache:clear, config:clear, view:clear, and even route:clear. no change.
• composer update/dump-autoload: tried updating composer dependencies and dumping autoload files, thinking maybe a package conflict. nope.
• permissions: double-checked storage and public folder permissions, they seem fine (755/644).
• rollback: even tried rolling back to the previous commit where it *was* working, but the issue persists. this makes me think it might be server-side or a dependency that wasn't properly versioned/rolled back.
• manual generation attempt: tried to run the sitemap generation command (if any) manually, but it's not even getting to the point of generating a file.

i'm seriously stuck and need help!

has anyone encountered something similar with dynamic sitemap generation in Laravel after an update? could it be a specific php version conflict, a hidden composer dependency issue, or something really obscure i'm overlooking?

any pointers, debugging tips, or alternative strategies to get our Laravel SEO back on track would be massively appreciated. i need to get this fixed asap before our rankings take a hit.

thanks in advance!
