I don't see a 3rd party firewall program installed. You might do a full scan of your system with Windows Defender Offline at boot just to help make sure it's clean.
If you are clean, then you could try doing a system restore using a restore point (if available) dated when you know Windows Firewall was working properly to see if that will fix the issue.
