BUG : System.IdentityModel.Tokens.Jwt 6.12.1 causes exceptions

I have several API projects where this package was installed. I recently updated to 6.12.1 from 6.12.0 through nuget and started getting exceptions.

System.InvalidOperationException: IDX20803: Unable to obtain configuration from: 'System.String'.
 ---> System.MissingMethodException: Method not found: 'Void Microsoft.IdentityModel.Logging.IdentityModelTelemetryUtil.SetTelemetryData(System.Net.Http.HttpRequestMessage)'.

Oddly, I found that I actually no longer need this package at all, and have removed it, thus solving my issue. But I’m wondering if 6.12.1 has some dependency problem when installed.

Confirmed. If I take another explicit dependency on

<PackageReference Include="Microsoft.IdentityModel.Protocols" Version="6.12.1" />

the exception is resolved.

In my case, it may have been related to a cached instance of our repository manager on my local machine. Once the bad package was removed from nuget and I invalidated my cache, builds succeeded again.

My repro was to reference a dependency which referenced this package. Beyond that I can’t say unfortunately.

Can you please share a list of all your package references and versions to packages named Microsoft.IdentityModel and System.IdentityModel?
