IRC Chatbot can see messages but can't PRIVMSG

Hey, so I tried tmi.js again and this issue persists. Tried turning on two-factor authentication and changing account.

When I send a message through tmi.js, I can see it in the log of the library, but the message isn’t actually visible in the chat. Happens in every chat, although I made sure to join ones that aren’t follower-only and are free for everyone.
