Unyson plugin for WordPress

[ADScirea]

After the update of PHP to version 7.4 and WordPress to 6.0 the plugin Unyson gave an error to the health site. A message says the is detected an active PHP session: A PHP session was created by a call to the session_start () function. This interferes with REST API and loopback requests. The session should be closed by session_write_close () before making any HTTP requests. If I disactive the plugin, the error disapper.
