I have this log under KDE. Sending files works only through Dolphin's context menu and from the phone to the PC.

My logs when I try to send a file to my phone

```
qt.qml.typeresolution.cycle: Cyclic dependency detected between "qrc:/qt/qml/org/kde/desktop/private/TextFieldContextMenu.qml" and "qrc:/qt/qml/org/kde/desktop/MenuItem.qml"
qrc:/qt/qml/org/kde/kdeconnect/app/FindDevicesPage.qml:13:1: QML FindDevicesPage: Created graphical object was not placed in the graphics scene.
qrc:/qt/qml/org/kde/kdeconnect/app/FindDevicesPage.qml:19:9: QML DevicePage: Created graphical object was not placed in the graphics scene.
```

I also get a notification on mobile to open the file, but it's empty. The folder "Drop" is also empty. I tried to re-pair devices, reinstall the package, clean data in `.cache` and `.config`, but it didn't change anything. 
Note: everything else works just fine: notifications, calls, clipboard sharing, etc

Recently I found a [related issue](https://forum.endeavouros.com/t/getting-kdeconnect-to-use-kvantum-theme-outside-of-plasma/57717) about a mismatching qt theme with a sort of "fix" for this

Similar issues posted earlier:
- [from January 2024](https://discuss.getsol.us/d/10206-kde-connect-sms-dark-theme-not-working)
- [from 2021](https://forum.endeavouros.com/t/kdeconnect-in-dark-mode/20363)
- [from june 2022](https://forum.manjaro.org/t/how-to-apply-themes-for-kde-applications/113794)

I use `kvantum` and seems like `kdeconnect-app` and `kdeconnect-sms` don't follow its theme like they used to do (without any tweaking)

However, it kinda works in settings menu and sms

My current workaround is to simply add colors from a kde theme to `~/.config/kdeglobals`

The result

</details>

I also noticed that `kdeconnectd` stopped running automatically via dbus service when I run `kdeconnect-app`

Seems like it's a bug and it's described [here](https://bugs.gentoo.org/934785)

For me it works again when I change `Exec` field in `/usr/share/dbus-1/services/org.kde.kdeconnect.service` to kdeconnectd's full path

```conf
[D-BUS Service]
Name=org.kde.kdeconnect
Exec=/usr/bin/kdeconnectd
```

File transfer from KDE Connect App still doesn't work, but works fine from `kdeconnect-cli` or Dolphin

Debug info 

```sh
