I fixed this RuntimeError for myself today.

However I'm not a professional programmer, so my advice is limited, but I can tell you what I did.

I previously installed Anaconda3, CUDA Toolkit 11.8 and had already Visual Studio 2022 on my computer.
Based on various sources (including those provided below) and digging through some of the files, I figured there might be some problem with the current installations of CUDA and Visual Studio. So I uninstalled everything and reinstalled the older versions of CUDA Toolkit 11.7 and Visual Studio 2019. I also removed Anaconda3 en reinstalled Miniconda3 just in case some corrupt files might be left behind. After this the error was gone.

These are the sources I used:
Failed to build CUDA kernels for upfirdn2d. UserWarning: Failed to build CUDA kernels for upfirdn2d. #155
Here they give advice to reinstall many components, including the CUDA Toolkit. Some people also recommend using Visual Studio 2019 instead of 2022.
Add Windows support for MSVC compiler path search #17
This source recommends adding code to the custom_ops.py file (I tried this, but because I was having other errors as well I'm not sure if it worked and I decided to reinstall everything instead).
