I tried the snap package and the same thing seemed to happen. I plugged in the drive and the backup didn't start. But this time when I tried to manually start it, it said another duplicity instance was running. I kept the drive plugged in and later on in the day it tried to start an automatic backup but failed for the same reason.

Each morning I would get a notification saying that the backup will automatically start when the drive is connected. When I insert the drive, it is automatically unlocked since I have the password saved on the computer. But after waiting for around half an hour the backup doesn't seem to have started. When I open Deja Dup it says that the last backup was yesterday and the next backup is today. Clicking the Back Up Now button starts the backup. The drive is GPT partitioned with a single partition containing ext4 inside LUKS.
