malfunction with google oauth2

I've been trying here and there for several months to work this out.

I am on Plasma6, Qt6 & Wayland.

I run systemsettings kcm_kaccounts, then click "Add Accounts" then select google; nothing happens in the UI (no window pops up, etc)

In the terminal it reads

qrc:/qt/qml/org/kde/kirigami/dialogs/Dialog.qml:344:18: QML ScrollView: Binding loop detected for property "calculatedImplicitHeight"

qrc:/qt/qml/org/kde/kirigami/dialogs/Dialog.qml:401:33: QML Binding: Binding loop detected for property "value"

qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface: 0x0

"google"

I have built from upstream git as well as your fork. Do you have any suggestions where I might look to resolve this?
