NVENC doesn't work, just jumps from 0% to 100%.

It worked fine up until I had to move to a new PC yesterday, and now it just doesn't work.

I've made sure all my drivers are up to date, ensured I installed the correct version and everything.

Any other render that doesn't use NVENC works fine, but as soon as I try NVENC it skips from 0% to 100% and does nothing.

I'm using Vegas 18 and an Nvidia GTX 2070 Super.

Here is what the log file reports:

That's weird, I'm not a video editing expert but I always make sure to have any settings in regards to interlacing be disabled, and everything was working smoothly up until I switched computers yesterday..

Did they change something overnight?

Edit: Interlacing was on dispite Vegas telling me it was off.

Trying again with making sure interlacing is disabled, it makes it this far before Vegas crashes:

I tried again with a clip that has no interlacing and Vegas crashes instead..

Everything worked fine up until yesterday and installing everything onto a new computer so I'm not sure what I am missing..
