I uninstalled 4.3.12, rebooted, and installed 4.3.14 RC1 94905. Afterwards I get the error in supR3HardenedWinReSpawn. Error relaunching VirtualBox VM process 5 Command line: (the rest is in the picture). I've tried both with and without the extension pack installed and there is no change. I've also tried uninstalling and reinstalling with right click "Run as admin". I've tried launching all of the VMs I have and none work. There was another error I didn't get a screenshot of that said "failed install ntcreatesection".
What should I try next? I'd like to help test the release candidate.
