Generic interface desserialization failure

[Lexy2]

Consider the following scenario:
I have a method defined as
public Task<IList<string>> GetListAsync(), in an IRpcService. The client application is targeting net472, and the server application is targeting net10.0.
The server implementation is returning just new List().
The client is calling var list = await GetListAsync();

Expected result
Empty list is returned.

Actual result

System.Runtime.Serialization.SerializationException: Cannot deserialize inbound call arguments. ---> System.Collections.Generic.KeyNotFoundException: Type 'System.Collections.Generic.List`1[[System.String, System.Private.CoreLib]], System.Private.CoreLib' is not found.

   at ArgumentList ActualLab.Rpc.Infrastructure.RpcInboundCall.DeserializeArguments()
   at Task ActualLab.Rpc.Infrastructure.RpcInboundCall.Process(CancellationToken cancellationToken)

If I change the interface to request Task<List<string>>, the call succeeds.

Tried with 12.1.61.
