Featured Snippets not loading

Hello! When I am doing experience training for my search experience, the Featured Snippets tab almost never loads. After one minute, I receive a “Something went wrong” error message, and no rows are returned:

It seems like it is timing out before it can load the results since it always happens around one minute into the loading process. Is there a way around this? I really want to improve our search experience’s Featured Snippets. Thanks!
