    Hi,

    How did you perform the upgrade, through visual studio using nuget. Or manually using the downloadable zip file ?

    I'm having the same problem. Though only with one of my two Umbraco sites. I upgraded them using the Nuget Package manager in VS2019 from 8.11 to 8.12.

    I too have deleted the Bin, obj, and client Dependency directories but still had the same issue.

    Same here. Are you'll using Unattended Upgrades? I wondered if that was related.
