BUG - Vegas Pro fails to launch: 'Intializing external monitoring'

Yesterday my Vegas products quit working: Vegas Pro 14, Vegas Pro 13 and Movie Studio 13 all hang on startup while displaying 'Initializing external monitoring' on the splash screen. (I keep version 13 for older projects that i don't want move to Vegas Pro 14).

All three programs worked flawlessly a week before (Macbook Pro Retina 2013 / Windows 10 Pro). What i did before: Installed and ran Avisynth 2.6 and Virtualdub FilterMod, uninstalled Avisynth after having said problems with Vegas.

What i have tried to solve the problem: Restored Vegas to defaults (Start with Ctrl+Shift), Rebooted several times, Updated Vegas Pro to the latest Build 270, ran a virus scan, updated Windows to the latest Build (Creators Upgrade), restored Vegas to defaults...

And yes, I read the previous Posts on that error in the forum.

Nothing helped. Any ideas? This is a serious problem, because i have work to do and have to switch to an older Computer.
I figure, this might be one DLL that fails to launch. Would Vegas start without that component, what would be missing?

Just a guess. Windows may have installed a new video card driver that is now causing you issues. Try and roll back the video card driver.

Thank you, OldSmoke, that pointed me in the right direction. While I still don't know, what exactly went wrong, I found the culprit:
I have an i-Tech USB 3.0 docking station with my external hard drives attached to it. This device has an USB to DVI port, which identifies as 'USB 3.0 Dual Video Dock' and an audio port by the name of 'DisplayLink Audio'. The drivers are just a few weeks old, so it is safe to assume, that they may have come with a recent Windows Update. I don't use these ports, so I didn't think of them as possible problems. After removing the docking station, VegasPro and Movie Studio were able to run. Both displayed the Master Bus audio slider as a floating window in the middle of the screen (where i did't put it), so obviously Vegas somehow tried to connect to the docking station and failed.
Interestingly enough: After succesfully starting VegasPro, I could re-attach the docking station and use files from a connected harddisk.

I am glad you got it working!
