Question / Help Setting up OBS with NVENC (Starting output failed)

I've looked at several guides and still can't quite get OBS to stream on my new laptop-- I used the same settings on my old one (Windows 8.1) but using it on Windows 10 and with a new NVIDIA card and I've had errors left and right. Every time I try to stream, it says my starting output failed and to check my drivers, but as far as I'm aware all my drivers are updated.

Here's my most recent log:
