Unfortunately, it seems like an IL2CPP build cannot start a process. https://forum.unity.com/threads/win32-il2cpp-process-start-not-work.539258/ The options are to use a Mono backend, or to set YoutubeDl.UseLocalInstance to false on IL2CPP.

I will make YoutubeDl.UseLocalInstance be set to false by default on IL2CPP in a future release.

Thanks for the follow up, setting YoutubeDl.UseLocalInstance to false is a viable work around for me!
