    I asked the same here:

    https://our.umbraco.com/forum/using-umbraco-and-getting-started/114237-the-call-is-ambiguous-between-error-at-addbackoffice-in-startupcs-after-updating-to-umbraco-14

    For me, the issue was that I was using another NuGet package (in my case Umbraco ExaminePDF and NestingContently), which referenced an old version of Umbraco.Cms.Web.BackOffice. After uninstalling those packages, it worked again.

    Removing NestingContently solved this issue for me. :)

    Hi. I am also having the same issues as this one. nuget package I tried to trace it, and it seems to be caused by the Umbraco.Cms.Web.Backoffice. Which is as of this writing, the latest is 13.5.2. I tried to uninstall it and it resolves the ambiguity error.

    My problem is that, the namespace is being used in our code. So I am also stuck.
