My posted test above was just to confirm that N10 has no inherent audio recording flaws as compared to previous versions. At least on a known system, such as Win 7. Win 10 and OSX both receive a steady stream of updates. Sometimes that breaks things and then either the OS maker or the software developer has to fix it. “It just works” left the building long ago.
Or, it could just be a bad combo of hardware and drivers. If you’re having dropouts when recording just a single track, something is very off. Your 32 core CPU is rare in a DAW and that does make you a potential guinea pig for changes by Microsoft. I’ve been there and done that myself.
Test your DPC latency. For sure your best move at this point.
