in the datasets only a rotating circle appears and they do not load

hello, after activating the mysql importer, and deactivating it again I only get the following screen, I read that it may be cache, but when trying to clear the cache, it remains the same, perhaps they are specific cache options, I deleted the cache using the command drush cache:clear
and the options described there. minus the theme-registy, for fear of breaking the site, I appreciate your collaboration

okay, it was because, the dataset was no indexed, reindexed and it work with " drush search-api:reset-tracker " and after
" drush sapi-i "
