And here is the open source code.

Thank you very much for your time.

With most errors like this when using disnake, my best guess would be that it's actually a problem with how your bot starts. Usually it's the result of using asyncio functions on a different loop that the one used by disnake, most often (in my experience) by doing some sort of async initialisation using loop.create_task and then forgetting to set up this loop as the running one or forgetting to explicitly pass it to Bot.
