Partclone Error Saving Ubuntu 20 Disk as Image

[mike]

Hi All,
I'd like to ask if anyone has encountered this error trying to clone a working drive to an image with Partclone.
Save Disk To Image > Basic
Error - Invalid Argument

Cloning using dd has worked, but restoring the image to another SSD results in a very long time even on another SSD (approx 2-3 hours).

Details:
Clonezilla Version - 2.6.7-28-amd64
Partclone Version - 0.3.14

Source Disk Details:
OS Installed Ubuntu 20.04.1 LTS; Desktop's Compatibility Support Module (CSM) is on, but I think this was installed via UEFI
Probably 200+GB Free Space
Samsung 850 EVO 250GB

Target Disk Details (Image Repository)
I have tried the following, but same issue persists:
120GB Flash Drive
4TB External USB formatted in NTFS

Would there be any workaround to this? Can I provide any other information to help troubleshoot this?

Thank you very much!

Edit: Apologies, this was supposed to be in the Clonezilla Live section, but the anti spam triggered when I was posting and reset the location of the thread, which I failed to notice... :/

Please take a photo about the whole messages on the screen then post it. It's easier for us to understand the whole process.
BTW, please also give testing Clonezilla live a try if you can, e.g., 2.7.0-3 or 20201016-groovy.
//NOTE// Backup important data before you use Clonezilla. Just in case.
