.Net7 ReflectionTypeLoadException: Unable to load one or more of the requested types.

Obfuscar unnecessarily renames methods that are implemention of some external interface. I get an exception:

System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types.
Method 'GetObjectData' in type 'A.e' from assembly 'X, Version=2.10.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

For example, I have TestSerializable which implements ISerializable from System.Runtime.dll

namespace Test
{
    public class TestSerializable : ISerializable
    {
        public void GetObjectData(SerializationInfo info, StreamingContext context)
        {

        }
    }
}

After obfuscation (without any error) I get:

1. for .NET 7 (assembly X.dll)

[X]Test.TestSerializable -> [X]A.e
{
	[X]Test.TestSerializable::GetObjectData[2]( [System.Runtime]System.Runtime.Serialization.SerializationInfo, [System.Runtime]System.Runtime.Serialization.StreamingContext ) -> A

	[X]Test.TestSerializable::.ctor[0]( ) skipped:  special name
}

GetObjectData method should be skipped but is renamed to A!

2. for .Net Framework (assembly X.exe)

[X]Test.TestSerializable -> [X]A.e
{

	[X]Test.TestSerializable::GetObjectData[2]( [mscorlib]System.Runtime.Serialization.SerializationInfo, [mscorlib]System.Runtime.Serialization.StreamingContext ) skipped:  external base class or interface
	[X]Test.TestSerializable::.ctor[0]( ) skipped:  special name
}

Renaming GetObjectData was skipped, OK.

To fix this I have added System.Runtime.dll path to AssemblySearchPath:

<AssemblySearchPath path="C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\7.0.12\ref\net7.0\" />

This is happending for me too.
Worked around this by chaging the class to public.
