Async method in K-Relay

[epicpawn]

Writing a K-Relay script that downloads the closed captioning off of a youtube video and plays it back in chat. My problem is that the one of the libraries that I am using uses asynchronous methods. K-Relay does not seem to like this and will not load anything past my plugin. The library is YoutubeExplode.
Thanks!

Edit:
I guess i forgot to put a question in here. I was wondering if there is any way to call the method, and get the same return, without using an asynchronous method. Otherwise is it possible to edit the library and remove the asynchronous methods? Would this damage the functionality of the program?

Figured I'd bump this with the error shown. Does anyone know if there is anyway to get around this. I am unable to call an asynchronous method within KRelay. Is my only option to use a different method/library that does the process synchronously.
Thanks

Have you tried something along the lines of

private void startCaptionDownload(Client client, string command, string[] args)
{
       captionDownload(client, command, args);
}

and then

proxy.HookCommand("capspeak", startCaptionDownload);

I think that it waits until the hook's callback method returns before moving on, so even if you were to use an async method, it's going to wait until the end. If you do what I did above it should start the captionDownload, then return immediately.

[epicpawn]

Tried that already and it brought up the same error. Not sure why, as I'm not too sure as to how async methods work with KRelay and such, but I think that the error has nothing to do with running the actual code. Instead KRelay looks through it, sees there is an async method and says "shit". Not even the initialize method gets run. Currently looking for another library or something to download youtube captions that is not asynchronous so if anyone knows anything about that it would be helpful.
Thanks

Figure I'm going to go back to using the python script as the method for downloading the captions unless someone can show me a better way, this means people will have to have python in order for the plugin to work. Oh well.
