Bug description

Currently it's not possible to connect more than one nextcloud.
The problem seems to be the broken window. That causes buttons and text to disappear and therefore makes the set up impossible.

Try connecting a second nextcloud.

Expected behavior

It should work like in previous versions (33)

do you mean that you do not see the "Add account" option anymore?
Even if you right client on the tray icon?

For me this option is there, but does not open the dialog to add more accounts.

Failed to load QML account wizard: QList(qrc:/qml/src/gui/wizard/qml/AccountWizardWindow.qml:22:5:
Cannot assign to non-existent property "minimizable"

Root cause confirmed: QML bug in this build. AccountWizardWindow.qml line 22 tries to set a minimizable property that doesn't exist on the window type in this Qt version — QML component
fails to compile, wizard silently never opens, no crash. This is a packaging/version-mismatch bug (Qt 6.10.3 here), not something misconfigured on your end.

• Package: com.nextcloud.desktopclient.nextcloud on Flathub, branch stable
  • Runtime: org.kde.Platform/x86_64/6.10, Qt 6.10.3
  • Symptom: "Add account" does nothing — no window, no crash
  • Root cause: AccountWizardWindow.qml fails to compile at load time
    • build 34.0.2daily (commit 104e4e87...): Cannot assign to non-existent property "minimizable" (line 22)
    • build 34.0.1daily (commit 661f0361...): BrowserAuthFooter is not a type (line 227)
  • Both are QML/Qt-runtime incompatibilities in the same file, on the two most recent Flathub builds — points to a QML-vs-Qt-6.10 regression in the packaging, not user config.
  • Confirmed via --logdebug --logfile: wizard aborts entirely on QML load failure, no account/credential logic runs.
