The issue seems to be related to older packages I had installed, particularly

<PackageReference Include="Microsoft.Extensions.ServiceDiscovery" Version="10.0.0" />
<PackageReference Include="OpenTelemetry.Exporter.Console" Version="1.14.0-rc.1" />
<PackageReference Include="OpenTelemetry.Exporter.OpenTelemetryProtocol" Version="1.14.0" />
<PackageReference Include="OpenTelemetry.Extensions.Hosting" Version="1.14.0-rc.1" />

Removing these creates a new error, but will raise separately
