What is your used hardware to probably see if there is no other GPU available that now is not yet available because it is not allowed in your BIOS. Otherwise try to update your Intell drivers if you are using an Intel CPU.
Sorry, I did make some progress though. After removing my GPU and only using the hidden dedicated Intel card to run everything I could get the program to boot up. I disabled GPU accelerated video processing in Options > Preferences > GPU accelerated of video processing >Off but after reinstalling the GPU it still crashes on startup with the same problem, when I uninstalled the GPU again it still launches with no problem, and GPU accelerated of video processing was still disabled, but with the GPU in it still crashes there. GPU: 1050Ti Processor: i7 7700 RAM: 8GB DDR4 if that helps
Again and again your are talking about "GPU". But as I expected before you have there 2 GPU's - the Intell HD Graphics 630 and - the NVidia 1050Ti.
To see which one is giving your problems you have to disable them one by one in the Windows Device manager and trying to start the program both times. At this moment not yet important to swich off things in Vegas untill you know which of the 2 GPU is causing the problems.
Sorry maybe I'm misreading this but for me removing is not the same as disabling, but if he did disable it in the Windows Device Manager I withdraw what I wrote. And that disabling one or the other gives other renderoptions in Vegas Pro 16 See here disabling the Intel
And see her for anabling it again and disabing the NVidia
tried to disable accelerated GPU video processing in options and it did disable it, but when I put the GPU back it still crashed the same way
That is because that setting in Vegas has nothing to do with your problem with the GPU that is starting the program of Vegas. On a laptop you can set that easy with a rightclick on the starting pic of Vegas, but on a desktop it is more difficult by switching the connection to your main monitor to or from the motherboard. How is that situation with you?
@Edrich-Guse What GPU is set as primary in your bios? There are so many combinations of bios settings, driver settings and Vegas settings but usually only one works well.
Some bios will always use the discreet as primary when installed, that means you monitor should be connected to it too. Some users have good results by using the Intel GPU as primary, have the monitor connected to it, set GPU acceleration to the Intel GPU and still render to NVENC via the Nvidia card. In such a scenario, the Intel GPU is used for FX processing and the Nvidia card for encoding.
