     Hello,

Fresh instalation of SOGo 5.9.0 from sources, RockyLinux 9.2.
When runned, these lines appeared in the log:
sogod [1712]: [so-product-registry] could not load product: MailPartViewers
sogod [1712]: [ERROR] [so-product-registry] failed to load product 
MailPartViewers required by MailerUI.
sogod [1712]: [so-product-registry] could not load product: MailerUI
sogod [1712]: [so-product-registry] could not load product: PreferencesUI

How to debug it?
