In about 75 seconds the NanoVNA Saver main screen finally shows up. But when I try to connect to the VNA comm port it quickly times out:
NanoVNASaver.Hardware.NanoVNA_2 - ERROR - Timeout reading version registers. Got: b' '
NanoVNASaver.Controls.SerialControl - ERROR - Unable to connect to VNA: Timeout reading version registers
<more debug stuff if you want it>
This is on a freshly booted NUC i5 2.2GHz 16GB RAM 64 bit Win 10 Pro
VNA-qt runs so the VNA, USB cable, etc are OK.
