.Net 6, C#, WindowsForms, Loading dlls from a sub directory using "probing" doesn't work?

I know this kind of question has been asked many times already, but for older versions of .NET and on 4.8 my project has been working fine with such in app.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <probing privatePath="languages;bin;"/>
    </assemblyBinding>
  </runtime>
...
</configuration>

but after I update to .NET 6 - its stops, anybody knows how to make it work on .NET6?
