With the latest win64 build, Blender 2.82 I get this error when press F12:
CUDA driver API error CUDA_ERROR_NOT_INITIALIZED (code: 3, file:D:\a\1\Luxcore\src\luxrays\core\context.cpp, line: 112): initialization error
I render with CPU; I have no GPU.

This apparently happen if you have CUDA installed but no NVIDA GPU available. Do you have ever installed NVIDIA drivers on that PC ?
