On one of my machines, the Wireguard Windows client 0.0.35 was previously working well, but as of today whenever attempting to activate any tunnel it generates errors with log messages like:
  2019-11-11 17:32:48.033: [TUN] [tun22] Unable to create Wintun device: Unable to create Wintun interface: GetStringValueWait(NetCfgInstanceId) failed: Timeout waiting for registry value
An uninstall - reboot - reinstall has not corrected this/

The affected machine has received some Windows 10 updates recently as well as a VMware Player update.But another machine with the same software installed works fine.
Any thoughts or suggestions?
