I ended up reaching out to the itch Discord, and although I'm not sure why, I was apparently autoflagged for spam and I imagine that was the reason for my issue. After this issue was resolved, I did end up getting responses to my ticket.
I'm not sure how to close a thread, if that's even a thing on itch? But my issue was resolved. 😊
