This SQL request call all time and overload my server : SELECT meta_value FROM wp_sitemeta WHERE meta_key = ‘wp_installer_network’ AND site_id = 1

What is it

It’s most likely a part of the WPML. This is based on a quick copy paste of wp_installer_network into the github search box.

There’s also a small chance this is the Types plugin, but you mentioned you had a multilingual plugin installed.

No references to wp_installer_network are found in WordPress itself.

and how delete it ?

You would need to ask this in a WPML community but the easiest way is to deactivate WPML. If you want to keep WPML but still resolve the problem you will need to ask this in a WPML community as 3rd party plugin questions are offtopic here
