Welcome to the forum @addelamar
Does your Destination screen 2 say “Microsoft OneDrive” or “Microsoft OneDrive v2” which is required?
What Duplicati version is this? I think 2.0.4.5/23 supported both, but Microsoft discontinued the old version.
Like this?
OneDrive failing : “The remote server returned an error: (410) Gone.”
EDIT:
2.0.5.1 removed support for the obsolete OneDrive and fixed various issues.
If you are on Linux, the mono package version requirement for it went up to 5.
