Warnings and errors keep popping up when backing up and restoring Windows 10

Hi, I started using Duplicati yesterday and received numerous warnings and errors when I’m backing up my Windows 10 to Google Drive. Even though Duplicati displayed that there are 3 versions of backups available when I tried to restore one of them, warnings keep popping up. I’m not sure if my backup is usable or corrupt. Can someone help please?

Never seen this myself but might be worth watching the live log and seeing if it shows anything - if you right-click the About and choose to open in new tab/window, you can go to the live log and set it to “verbose” or “profile”, then go back to the first window and try it again. Switch back to the other tab/window and see what it says.

Here’s what Duplicati outputs when I tried to restore my files:

Take a look here as it might be related: --auth-password is not supported

Thanks. I will give it a try.
