It'q clear :

digikam.general: Starting to load external tools.
digikam.general: Parsing plugins from "/opt/qt5/plugins/digikam/"
digikam.general: Plugins found: 0
digikam.general: No plugins loaded. Please check if the plugins were
installed in the correct path, or if any errors occurred while loading
plugins.
digikam.general: void Digikam::DPluginLoader::Private::loadPlugins()
Time elapsed: 0 ms

in the path, no shared files are fond as plugins (.so)

Look in source code how is determined this path :

https://invent.kde.org/kde/digikam/-/blob/master/core/libs/dplugins/setup/dpluginloader_p.cpp#L59

Two ways are possible : an environment variable : DK_PLUGIN_PATH or
the Qt plugin path set in your system.

The 2nd solution is used in your case which want mean a mess in your
Qt configuration.

You can solve your problem to setup the DK_PLUGIN_PATH bash variable
before to run digiKam...

About the way proposed by Maik to check the bootstrap.sh script to
configure the compilation with cmake, look here :

https://invent.kde.org/kde/digikam/-/blob/master/bootstrap.linux#L49

So, there is a detection of this Qt plugins path using qtpaths
executable provided by your system...

Best
