Site Suddenly Has No RSS Feed

OMG, I have tried everything but my site appears to have no RSS feed all of a sudden. Here is what I’ve already tried prior to asking the forum community for help:
https://wordpress.org/support/article/wordpress-feeds/ the feed urls provided (with my site url of course) produce blank pages.
https://mailchimp.com/help/troubleshooting-rss-in-campaigns/?utm_source=mc-kb&utm_medium=kb-site&utm_campaign=eepurl some of my blog posts are password-protected and some are not. MailChimp’s feed validator says the feed urls I tried (according to various articles providing such as above) ‘looks like a web page not a feed.’
https://perishablepress.com/what-is-my-wordpress-feed-url/ I tried urls from the various types given but still got failed validation as above.
https://wordpress.org/support/article/settings-permalinks-screen/ I did not see any of these options in my WP dashboard.

Please if you understand the issue provide step-by-step instructions for fixing whatever is wrong, not skipping any step. I really appreciate it.
