I am not even using GPU render, I am using CPU render but I am getting this. I dont know but I started getting issues after installing the latest Studio Driver from Nvidia. I am using the following Arnold and Nvidia driver versions - Arnold Core 126.96.36.199 (MtoA 188.8.131.52), Nvidia Studio driver-451.77
This is the error I am getting when I hit IPR.
// Error: [gpu] an error happened during GPU context setup : Unknown error (Details: Function "_rtBufferCreate" caught exception: Encountered a CUDA error: cudaDriver().CuDevicePrimaryCtxRetain( &context, dev.get() ) returned (999): Unknown, file: <internal>, line: 0) //
