Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).

I reinstalled Calibre and the issue with configuring preferences for sending book to device now works. I am still unable to send books to a device as Calibre reports the

libusb_claim_interface() reports device is busy, likely in use by GVFS or KDE MTP device handling alreadyLIBMTP PANIC: Unable to initialize device
I can connect to the device through other means so not sure if this is an Ubuntu issue, a device issue, or a Calibre issue. I will keep trying

I found a solution
Plug the device in, then unmount it, then start Calibre

The error message indicates that the SaveTemplate.__init__() function is not expecting the parent keyword argument. This is likely due to a bug in the Calibre software.

There are a few things you can try to fix the issue:

Upgrade to the latest version of Calibre. The bug may have been fixed in a newer release.
Try disabling any Calibre plugins that you are not using. It is possible that one of the plugins is causing the error.
Reset Calibre's preferences to their default values. This may fix any corrupted settings that are causing the problem.
If you are still having problems, you can try reporting the bug to the Calibre developers.
To reset Calibre's preferences to their default values:

Close Calibre.
Go to the Calibre configuration folder. On Linux, this is typically located at ~/.config/calibre.
Delete the preferences.json file.
Restart Calibre.
If you are unable to fix the issue, you can still send books to your Android device by using a different method. For example, you can copy the books to your device manually, or you can use a cloud storage service such as Google Drive.

Here are some instructions on how to send books to your Android device using Google Drive:

Connect your Android device to the same Wi-Fi network as your computer.
Open Google Drive on your computer.
Upload the books that you want to send to your device to Google Drive.
Open Google Drive on your Android device.
Tap on the books that you want to download to your device.
Tap on the three dots in the top right corner of the screen.
Tap on "Make available offline".
The books will be downloaded to your device and will be available to read in the Google Play Books app. by https://www.crescent-builders.co.uk/
