When I use an older Arduino version (1.6.13), I do not experience any issue. E.g. the Blink sketch uploads without any issue, and executes on the Nano.I see the issue of 'programmer is not responding...' in versions 1.8.9 (Windows Store 1.8.21.0) and on the Arduino WEB.
In the beginning of 2018, Arduino changed the bootloader for the Nanos. Clones and older originals use what is called the 'old bootloader' in newer IDEs (see reply #47); in older IDEs it was 328P (or something like that). New originals use the 328P bootloader in the newer IDEs.
