Unfortunately there seems to be an issue with version 19.1 quitting at startup if the --no-nvml parameter is used. When I include that parameter, "WARN - NVML is disabled" is displayed and then the next line is "Press any key to continue...". If I don't include --no-nvml, the miner runs fine with all the other parameters. I tried this with both the Cuda 10 and Cuda 10.1 versions for Windows. This was not an issue with previous versions of your miner, so I wanted to let you know.
