Possible work around during crisis
Until the issue is resolved, you may be able to get back up and working with DW the way I did, if you have a backup. I closed DW. Restored the configuration directory/shared/webassist files from backup and used my firewall to block DW from accessing the Internet for now.
I actually only restored selected files/folders from configuration directory/shared/webassist, but if you aren't sure which ones to restore, all is safer as long as your backup is fresh enough.
