Good afternoon,

I have services in .net6 and in this moment I'm using the next nugets:

- Elastic.Apm.NetCoreAll (1.20.0)
- Elastic.Apm.SerilogEnricher(1.5.3)

I would like upgrade the packages but when I use the version 1.22 of NetCoreAll I have this error:

The singleton APM agent has already been instantiated and can no longer be configured.

I know that the message means that I'm creating 2 instances, but I think that the problem is the compatibility of the two libraries?

In serilog the next version is 8.6...

Someone has the same problem?

Thanks for all!

I saw the problem. Was an error code, I have a middleware that create another transaction but only in the version 1.22

Thanks!
