WordPress Error after deactivating plugins

Hello,

I have been installing, activating and deactivating plugins to test them, suddenly, this happened:

Please, can anyone help me with this?

Usually this happens when a plugin breaks someting.
I suggest install only the supported plugin through the "plugins" section, and not upload plugins from the web.

I also suggest using "WordPress managed hosting" (both account types are free). With this type of account, you can repair your site using this procedure: https://aa.altervista.org/blog-recovery.php
