If your iPhone is experiencing “Call Failed” issues during calls on social media apps like WhatsApp, Snapchat, Instagram, etc., and after the call fails, you cannot call the person again unless you remove the app from recents and reopen it, this appears to be a bug introduced in iOS 18.

This appears to be an iOS 18 bug, as the “Call Failed” issue is occurring across multiple calling apps like WhatsApp, Snapchat, Instagram, and others. Since it’s affecting all third-party calling apps, it’s likely a system-level issue introduced with the iOS update.
