Can't connect 1.16+ servers with 1.8.9 ViaForge

[ぷいぷいワーカー]

I tried Debug with Idea and Test with Build, but I got this error in both. Protocols below 1.15.2 work normally.
Also, the GuiProtocolSelector versions are inconsistent, does this have anything to do with it?

Can you try the latest version of ViaForge and if it doesn't work try it without any other mods?
