I can't get this scraper to work, it randomly works

Hello, I'm trying to scrape data from this website Patient Communities - Our community of patients, carers, and health-conscious individuals is here to help. But it doesn't work. Sometimes it starts getting inside the categories and begins scrolling, but stops after two scrolls. Sometimes it doesn't even get inside the categories. I tested previewing data for each part individually, and it correctly retrieves the data, but the scrape function doesn't work. Any idea where the problem might come from? I tried it in both Brave and Edge

Url: Patient Communities - Our community of patients, carers, and health-conscious individuals is here to help.

Sitemap:
{"_id":"patientinfo","startUrl":["https://community.patient.info/"],"selectors":[{"id":"Categories","parentSelectors":["_root"],"type":"SelectorLink","selector":"a.category-title-link","multiple":true,"linkType":"linkFromHref"},{"id":"PostsLinks","parentSelectors":["PostsElements"],"type":"SelectorLink","selector":"a.title","multiple":false,"linkType":"linkFromHref"},{"id":"Post","parentSelectors":["PostsLinks"],"type":"SelectorText","selector":"#post_1 p","multiple":false,"regex":"","multipleType":"singleColumn"},{"id":"PostTags","parentSelectors":["PostsLinks"],"type":"SelectorGroup","selector":".list-tags a","extractAttribute":""},{"id":"PostTitle","parentSelectors":["PostsLinks"],"type":"SelectorText","selector":"a.fancy-title","multiple":false,"regex":"","multipleType":"singleColumn"},{"id":"PostsElements","parentSelectors":["Categories"],"type":"SelectorElement","selector":"td.main-link","multiple":true,"scroll":true,"elementLimit":0}]}

Hi,

There appear to be scripts constantly running in the background, resulting in errors that interfere with the scraping process. I would try opening the website with JavaScript disabled (you can install an extension for that) and build the sitemap from there.
