Had this issue last night. Make sure you’re not renaming the .py files. If that doesn’t work, update qBittorrent to the latest version, uninstall Python (and delete all folders associated with it in both Program Files and AppData), and reinstall Python, being sure to check the box that gives it access to Path.
The Demi Lovato talk was hilarious to watch. She’s an utterly charmless narcissist and literally asked a guest the question, “How bad would you have felt if I really had killed myself?”. It’s incredible no executive pulled the plug on it at any point during its production.
