Podcast Player : Feed data not available.

Hello, I have an issue with the podcast player plugin. The links to the podcast are broken on our website :

RSS Error:?A feed could not be found at https://spotifyanchor-web.app.link/e/eXOwJT01yvb; the status code is 200 and content-type is text/html; charset=utf-8

In the wordpress back-office, in the “toolkit” page of the plugin, I can’t neither update or delete the podcast, it says “Feed data not available. Either data already refreshed OR feed url is not correct.”

The RSS feed is OK, https://castfeedvalidator.com/ says so. I tried to uninstall the plugin, and it doesn’t work. When I reinstall it, the podcast is still there, not working and blocking the process.

The page I need help with: [log in to see the link]
