OneDrive reading file ERROR: IO error: unauthenticated: Unauthenticated

I'm suffering the same issue as here and in OneDrive personal - unauthenticated, download only - #9 where I can upload, I can do ls/lsd/lsf and I can even delete files. However I can't download/read them.

Unfortunately abandoning the account is not really viable for me. This a paid account on a family plan. The main reason I'm using rclone is to create one large storage space out of 3 across a family subscription (possibly not exactly within T&Cs). The two other accounts work perfectly ok.

What I've tried:

  • Recreated the token (including revoking access from the OneDrive settings).
  • Updated to the latest 1.65.2 release version and also a nightly build (rclone-v1.66.0-beta.7746.692af4285-windows-amd64) from a few days ago.
  • Tried from Linux and Windows clients (latter would be from a different IP to the former)
  • I can read the files from both the web client and from the app.
  • v1.66.0-beta.7595.5841b1253.fix-7405-onedrive-upload doesn't work

Any ideas? This has worked for about a year flawlessly until about a week ago.
