a more indepth crash log

Got this message when I try to open up my packaged game, in fact it just completely crashes and doesn’t open. However, in the actual editor, the plugin works and everything is just fine.

How I fixed it?
Don’t use a deprecated library. The DiscordRPC library hasn’t been updated for nearly 2 years now. Use a supported library!
