Hi @Kaden
Welcome to the Atlassian Community!
You can delete a team by going to your team's page in Trello, clicking on the "Settings" tab, and then clicking the "Delete this team" link. You must be an admin to delete the team. Deleting a team is permanent and there is no undo. Boards within the team won't be deleted
You can read this article/docs/guide to know more

and if you still won't able to fix the issue you can ask Trello support!
