Hi! I see you're having trouble logging into the Knives Out app and keep getting a "permission granted" message. Just to clarify, is the message exactly "permission granted," or is it something like "permission denied," or an error related to permissions when trying to log in? Also, are you logging in via a social account like Facebook or with a separate Knives Out account?

Understanding these details will help me guide you to the right fix. Meanwhile, I’ll share some common steps to address login permission issues:

1. Check Account Binding: If your Knives Out account is linked to Facebook or another social platform, sometimes the login can expire or lose sync. Logging out completely from both and logging back in might help.

2. App Permissions: Even on Windows with a WebKit browser, the app or game client might require certain permissions—network access, storage, or other. Ensure these permissions aren't blocked by your firewall or antivirus settings.

3. Clear Cache and Cookies: Sometimes corrupted cache or cookies related to the app can cause weird login issues. Clearing these in your browser settings can refresh the process.

4. Update the App/Client and Browser: Ensure that your Knives Out app or game client and your WebKit browser are updated to the latest version.

5. Check Network and Server Status: Occasionally, server-side issues can cause permission errors. Confirm that the Knives Out servers are operational.

If you've tried any of these already, please let me know which ones, and if you encountered any specific error messages beyond "permission granted." That way, I can provide more targeted steps or advanced troubleshooting.

Are you able to share a screenshot or exact wording of the message? That would help a lot!
