Short description of error
When rendering a certain animated mesh in Cycles and with motion blur turned on, the shader seems completely broken in the render output. Viewport render works without a problem (no motion blur of course). Also, rendering with Optix throws an error and does not work at all, while CPU rendering works but with a broken shader.
GPU rendering with Optix throws the following error:
CUDA_ERROR_ILLEGAL_ADDRESS in cuStreamSynchronize(cuda_stream[thread_index]) (device_optix.cpp:821)
Exact steps for others to reproduce the error
Open the attached file, ensure that CPU rendering is used (so it does render at all) and render with F12. If the problem does not show at the first try, render with GPU (Optix), switch back to CPU and render again.
