JA Tour "0 Serialization of 'Closure' is not allowed"

nexus6it

Have a nice day.
i did an update from joomla 4.0.2 to 4.2.2 and from php 7.x to 8.0. Before to start the update i did the update to all the components.
If i use the style template "Ja_tour home page" for my home page (for have the sam aspect of the demo page on your website) i have the error "0 Serialization of 'Closure is not allowed".
The main page of joomla administration report that there are 21 override (all in template directory)

At moment i set the home page to another page.
