Various errors in updating versions 2 and 2.0.2

I too have noticed several errors in updating the component to versions 2.0 and 2.0.2. I have tried several times, but either it breaks the site, making it inaccessible, or it cannot find certain libraries and renders the entire site's backend unusable.This is the error that appears most often:
Failed opening required '/home/urj6d51o/domains/studioliviero.sviluppo.host/public_html/administrator/components/com_route66/lib/seoanalyzer.php' (include_path='.:/opt/alt/php84/usr/share/pear:/opt/alt/php84/usr/share/php:/usr/share/pear:/usr/share/php')

Version 2.0.4 has not resolved the issue either: Furthermore, there is an issue with the language file.Attenzione JInstaller: :Install: Errore SQL Table 'std_route66_metadata_backup' already exists Installazione dell'estensione interrotta.

The problem is that right now I don't have much time to fix any site breakdowns.I'm trying on a staging domain, but if I have to intervene manually, I'll wait until September.
