EDIT: Fixed by renaming OFX folder and then deleting some plugins.
I just installed Vegas Pro 20.0 and it won't open.
I have had Vegas Pro 14 and 15 on this computer before but I have uninstalled them completely.
The loading screen gets to "Creating video plug-in factory..." waits for a few seconds, and then, poof, it shuts itself down without warning or fanfare.
I'm running a Desktop PC with a GTX 1060 and Ryzen 1600, and 16 GB of RAM.
