While the issue on my system was resolved, for a bit, shortly after booting up, it stopped working again. Same as before, Windows couldn't assign an IP address to the TAP network interface.
Further troubleshooting and I've been able to resolve the issue again.
It appears my antivirus might have been causing the issue. I was running Avast Business. I performed the same "deltapall", then uninstalled Avast. On reboot, I ran the "addtap" command and OpenVPN is working properly now. Seems likely the issue is related to the firewall functions of Avast.
Hopefully, this resolution will stick. With more time, I may reinstall Avast to see if the issue returns. Since the functions Avast installs are "burned" into the installer by the company I work for, I won't be able to disable portions of it for troubleshooting.
