Can not render via GPU ERROR Illegal address in cuCtxSynchronize() (device_cuda_impl.cpp:2016) All of a sudden, my system stopped rendering via GPU. It renders fine via CPU, it looks like the error has something to do directly with my graphics cards too. I have tried rendering via CUDA and OPTIX, no luck. I have tried 3 different versions of Blender (2.90, 2.91, 2.92 beta). I have reset my preferences, uninstalled, re-installed graphics drivers, roll back graphics drivers and nothing. I was able to test rendering. I ran heaven benchmark on direct x11, cinebench (Only openGL), and ran Counter Strike on high settings with no problem. I lastly ran Compubench 2.0 which I believe tests via the CUDA API. Computer specs and the error from the blender console below. Thanks to whoever can help me in this confusing endeavor.

Solved. I yet again reinstalled my nvidia drivers, except this time I made sure Windows did NOT automatically update my drivers, and manually updated with the latest. For the record, the Nvidia driver version I am now using is 432.00.
