sign: SignService server: error while signing "The application has failed to start because its side-by-side configuration is incorrect"

While trying to update our SignService instance to the most recent master branch code per https://github.com/dotnet/SignService/issues/60#issuecomment-489245289, ran into the following error running the latest code:

The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detailSystem.ComponentModel.Win32Exception (14001): The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detailat SignService.Utils.Kernel32.ActivationContext…ctor(String assemblyName) in d:\a\1\s\src\SignService\Utils\Kernel32.cs:line 77at SignService.AzureSignToolSignService.RunSignTool(AuthenticodeKeyVaultSigner signer, String file, String description, String descriptionUrl) in d:\a\1\s\src\SignService\SigningTools\AzureSignToolSignService.cs:line 105

I deployed to our Azure Website that we’ve been using to host the SignService instance using an artifact deployment via the https://github.com/dotnet/SignService/blob/master/azure-pipelines.server.yml file in this repository.

Is this a configuration issue with my specific deployment? Or an issue with the latest code?
