BufferingAppenderSkeleton.Append throws exception on arm64 linux by calling WindowsIdentity.GetCurrent

I have a .netcore 3.1 console app which works correctly with log4net 2.0.8. After upgrading this package https://www.nuget.org/packages/Microsoft.Extensions.Logging.Log4Net.AspNetCore/ to latest version I also had to upgrade to log4net 2.0.10. After that upgrade I started getting errors:

2020-09-28 15:17:24,191 [ERROR] MyProject.ElasticsearchAppenderBase - System.PlatformNotSupportedException: Windows Principal functionality is not supported on this platform.

at MyProject.ElasticsearchAppenderBase.Append(LoggingEvent loggingEvent) in /home/MyProject/Common/SharedPublic/Logging/Elasticsearch/ElasticsearchAppenderBase.cs:line 87

The same error occurs with log4net version 2.0.11.

The ElasticsearchAppenderBase is my custom class built on top of BufferingAppenderSkeleton.
