why is my dynamic sitemap breaking laravel seo?

oh man, i am totally stuck and seriously frustrated. my 'Dynamic XML Sitemap' for our laravel app is absolutely messing up all our hard work on laravel seo optimization, and i'm just hitting a wall here. we implemented this auto-updating sitemap solution, specifically something like 'Dynamic XML Sitemap for Laravel & All Websites', thinking it would be a huge win for indexing and overall visibility. instead, google search console is throwing up all sorts of bizarre errors, pages that should be indexed aren't showing up, and i just can't for the life of me figure out what's gone wrong.

i've been at this for hours, literally checked everything i can think of—file permissions, cron job schedules to make sure it's updating, even tried manually re-generating the sitemap a bunch of times. it seriously feels like there's some fundamental conflict or a really subtle misconfiguration i'm completely missing. what are the absolute first things i should be looking at when a dynamic sitemap seems to be actively hurting seo, especially in a laravel environment? are there any common gotchas or specific debugging steps for this kind of problem? thanks in advance!
