[Elecraft] "K3 VFO A Not Responding" message

[Tom H Childers]

Usually when a computer locks up it is not the fault of equipment
that is connected to the computer.  It is usually a problem with
software that is running on the computer.

Since you are controlling the K3 with a software application, the
software is the first place you should look for the problem.

Have you contacted the N1MM Logger folks to ask for help?  That would
be the first thing I would do.
