Restore attempt - Can't get past Select Files -> Waiting for task to begin

I recently suffered a failure on my home server that led me to having to completely restore it losing all my local data storage. Not to worry I thought - everything is backed up to AWS using Duplicati, and I regularly (ok - occasionally!) tested the Restore functionality so I was confident that all was not lost.

I’ve rebuilt my server (Ubuntu 20.04), reinstalled Duplicati, loaded up my backup configuration file, tested the connection … so far so good … but when I get the the Select files stage (step 3 of 4) everything stops at “Waiting for task to begin”

Not sure if I’m making a basic mistake here - do I just need to be more patient and wait longer? What is it waiting for? Or has the restore process hanged completely?

Please help!

Thanks
