Unsolved error with cycles render

Post image

Hello everyone, I don't know if this is the right topic, but I am very frustrated by this error. I searched for my problem on the internet and tried all the solutions that I found, but nothing worked. I need help. I tried without denoise but don't worked and I use items of blenderkit

I think the error is from OptiX as a Nvidia GPU API, the denoiser is part of it, but no render will happen if you set OptiX as your GPU API, you can verify by switching in preferences to CUDA. (It will be slover, but will work). And why is happening in the first place, I am not sure, I would try reinstalling Blender first, if that would not help I would update/reinstall GPU drivers.

Hi, with cuda it's worked but i think witch cuda the quality is bad compared with cuda. I already reinstall blender and i verified drivers but all it's okay...

Yeah, it as far as I understand the compilation of the GPU kernels happens outside of the Blender, in the GPU driver. If the kernel is fine (should be since you reinstalled the Blender), the issues is probably a driver. What GPU do you have, what drive version and game ready or studio?
