Are you saying that another computer connects to the K3 just fine? Or that
the first computer connects to a second computer? I am assuming it is the
former, but I had to ask.
Did this computer talk to the K3 previously?
Are you using a USB port that has been assigned as a COM port?
What does Device Manager show as a driver?
What does it call the port?
What cable are you using, and can you try switching to another cable?
Did you check Device Manager to find out what has happened to the original
COM5? Do you have other apps contending for that port?
It definitely sounds like a computer / cable issue, not a K3 problem.

Subject: [Elecraft] Com ports behavior
I have lost radio control on my K3. To find out why, I tried to connect to
the K3 Utility. Com5 connects just fine at 38400 bits/sec. When I try to
check for firmware, I get a "com5 is closed" message.
Have spent a few hours investigating this, but no joy. I can connect just
fine to a different computer. Both computers are Win10.
Why would a com port that connects just fine then show as closed?
