Have you tried using forward slashes for the path?
In the YAML language, backslashes have special meaning (they begin an "escape" sequence, mening that the next character is to be treated differently than normal) and to be interpreted literally they need to be prefixed by another backslash. While C:\\SIEM\\PQ will likely do what you want here, I find the POSIX-style path C:/SIEM/PQ easier to read.
