Hey, I recently tried to use OBS and found that it wouldn't work, I used a number of solutions, including updating my amd drivers and getting the AAS encoder. I tried again, it didn't start up but I couldn't find anything clearly wrong. Here's my log:

Is there anything that isn't right here that I didn't spot?

Seems like you still have some leftovers from an NVIDIA driver. With your new AMD card you can't use NVENC anymore, you need to change the Encoder.
