I think it's because nvcc isn't pulling outside of if I am in the cuda directory. I have added it to paths but may have the wrong environment variable or something.

copying the nvcc.exe into the folder was a long shot and a no-go

Based on your output it looks like CUDA was not installed. About 1/3 of the way up from the bottom of your screenshot it says it couldn't find CUDA on your system. Can you verify your CUDA install? You can run: nvcc --version on your CMD or bash terminal and it should give you some system info about your CUDA install. The repo says you can run it with CUDA 10.2 + but I have only run it will 11.6 and 11.8 without any problems.
