I took a look into that .deb file. They bring their own version of Qt which
is maybe modified, but I can't tell (see attached screen shot) and play with
LD_LIBRARY_PATH to use their version of Qt before they use the one installed
on the system.

This modification should only be local to the application and not affect the
whole system.

Yes, that won't make a difference, though AppImages bring their own version
of Qt as well, so it might help. But that would be just a workaround.

To investigate this further, it would be interesting what LD_LIBRARY_PATH is
set to when KMyMoney does not work. Also, the setting of QT_QPA_PLATFORM_PLUGIN_PATH
is of interest, as the error message points to that part. Also, can you provide
us with the output of 'ldd kmymoney', svp?

Here's what is contained in Olympia.sh

---8<---
#!/bin/sh
BASE_DIR=$(dirname "$(readlink -f "$0")")
export LD_LIBRARY_PATH="$BASE_DIR"/../libOlympia/:"$BASE_DIR":$LD_LIBRARY_PATH
export QML_IMPORT_PATH="$BASE_DIR"/../qml/:$QML_IMPORT_PATH
export QML2_IMPORT_PATH="$BASE_DIR"/../qml/:$QML2_IMPORT_PATH
export QT_PLUGIN_PATH="$BASE_DIR"/../libOlympia/plugins/:$QT_PLUGIN_PATH
export QTWEBENGINEPROCESS_PATH="$BASE_DIR"/bin/QtWebEngineProcess
export QTDIR="$BASE_DIR"
export QT_QPA_PLATFORM_PLUGIN_PATH="$BASE_DIR"/../libOlympia/plugins/platforms:$QT_QPA_PLATFORM_PLUGIN_PATH

"$BASE_DIR/Olympia" "$@"
