I have ATCS Monitor running on Windows 10 both in server mode and in client mode where my own radios feed into my ATCS Monitor instance, allowing me to monitor rail traffic on the UP main from my home between V290 and V310 . It works well under Win 10 and will even run under win 11 although it has some quirky behavior under Win11 that convinced me to fall back to win10. Usually if it comes up then comes right down, it will log the problem in a file in the ATCS Monitor directories.
