you also need to use the option -d (or the long form of it --opencl-devices) to select a specific device. The upper case short option -D (or long --opencl-device-types) does something completely different:
Therefore you need to use -d 12 (lower case d followed by the device number).
BTW: if you want to test your CPU only, you could just use -D 1 (but note: this means that hashcat should use a different type of device, not to select a specific device in the list like -d does... parameters for -D x are: 1: CPU, 2: GPU, 3: FPGA, DSP, Co-Processor)
Code:
-d, --opencl-devices | Str | OpenCL devices to use, separated with commas | -d 1
-D, --opencl-device-types | Str | OpenCL device-types to use, separated with commas | -D 1Therefore you need to use -d 12 (lower case d followed by the device number).
