Ciao Matteo, grazie per la risposta. Ho scoperto che il problema era causato da WP Bottom Menu.
Ti riporto il log che mi ha mandato WordPress. Ho già scritto anche allo sviluppatore del Plugin ma non hanno ancora risposto.

Versione di WordPress 5.7.2
Tema corrente: Divi Child (versione 1.0)
Plugin corrente: WP Bottom Menu (versione 1.3.1)
Versione PHP 8.0.7
