Hi Steve,
Thanks for posting back.
For the shortcut in OneDrive, its folder icon has a blue arrow and its name will be "libraryname - sitename". So, according to your reply, you don't see the library folder in OneDrive.
The limitation and the suggestion in my previous reply are based on the assumption that you have added the library as a OneDrive shortcut. For example, if you have already added a library as the shortcut to your OneDrive and set up your account in the OneDrive app, then you go to SharePoint and try to sync the library to local, the error "Sorry, OneDrive can't add your folder right now" will pop on. That's the limitation I mentioned, and why I recommend that you need to choose one of the methods (sync the library individually using the OneDrive app, Or add the library as a shortcut to your OneDrive and then sync your OneDrive files using the OneDrive app) to prevent the situation from happening.
If you don't see the library folder in your OneDrive (OneDrive for Web), you can avoid the limitation and the suggestion in my first reply. Since you have reset OneDrive, but the situation still happens, I would like to collect more information to troubleshoot.
I wonder if your colleagues are in the same situation when syncing this library.
If so, you don't need to try the following steps. Please post it back and let us know.
If not, please try the following steps, then check again.
a. Please unlink all accounts from the OneDrive app.
Unlink and re-link OneDrive
b. Please go to the following path and delete all OneDrive local folders.
Go to "C:\users\username" (edit the username part) and delete the related OneDrive folder. The folder should be OneDrive - XXXX or Tenantname - username.
If it reminds you that you can't delete the whole OneDrive local folder, please restart your device and try to delete it again.
c. Please run OneDrive and sign into your business account in the OneDrive app. After that, please try to sync the library again.
We look forward to your response. Thanks for your cooperation.
