This is still true even after the latest changes to GpgOL not to require Kleopatra or GPA through the UIServer protocol. The details dialog / search still uses Kleopatra or GPA as a fallback.

With Gpg4win 3.0 we have reworked the startup of Kleopatra. It is now much more robust. Please try https://wiki.gnupg.org/GpgOL/Development/Testversions and reopen this issue / comment if this is still a problem.

There are several reports about such problems. So far I'm unable to reproduce /
debug this. But we have to look into conditions that might cause this and at
least improve error reporting in these cases.
So far I can only think of that the UIserver socket file
(%APPDATA%\gnupg\S.uiserver) has permissions that kleopatra can not create it.

The updated translation is part of gpg4win 2.3.0

I've fixed this in the KDE translations.
Updated translations need to be put in gpg4win.

With gpg4win svn639 the problem described here is resolved, and
replaced by a different one that is really inside Kleopatra.
