1. U may need to try a different version of clumsy (A B C Versions are available)

2. Check your antivirus and make sure its not blocking anything

3. You can try uninstalling the driver:

I tried from a fresh download and it works for me. I suspect the problem is that there is an old WinDivert service that is pointing to a path that no longer exists. Try the following as Administrator:

sc stop windivert
sc delete windivert

If that does not work, try the following from the WinDivert-2.1.0-A\x64\ directory:

windivertctl.exe uninstall

If that does not work, try rebooting.

If rebooting does not work and as a last resort, use regedit to manually delete the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDivert entry and reboot.
