Thunderbird has an extremely slow startup when it can access Mac contacts

I am using Thunderbird 115.5.2 (64-bit) on Mac OS 14.1.2 (23B92).

Since its installation, its startup has been always slow: several seconds with a blank window and the spinning wheel. The startup is slow when Thunderbird has access to the Mac Contacts.

If you go to System Settings, Privacy & Security, Contacts and prevent Thunderbird to access the Contacts, then its startup time is decent. It seems overall snappier.

Clearly, without having access to Contacts, the use of Thunderbird is slightly annoying.

Why is it so slow when accessing Contacts? Is there anything I can do on my side to let it access the Contacts and stay fast?
