NanoVNA saver cannot connect to NanoVNA vis com port error


 

Well NanoVNA Saver 0.6.5 used to connect to com port on Win 10 and now it does not. I start the nanovna software, turn on the NanoVNA and when
I click Rescan the software crashes off. If I turn on the NanoVNA first and then start the software I get Failed to execute nanosaver could not open Com 5. When I check Device Manager com ports I see Com port 5 and the yellow triangle. I deleted the com port and plugged the C cable from the NanoVNA-H into the pc and the com port 5 reappeared with the yellow triangle.

So I downloaded Nanosaver 0.7.3 and with NanoVNA turn on then start nanosaver 0.7.3 I get the com port 5 error. If I start nanosaver first and then turn on NanoVNA-H I click rescan and nothing happens.

The yellow triangle on the STMicroelectronics Virtual COM Port (COM 5) is causing nanosaver not to connect to pc. I have downloaded latest nanovna saver driver and when I try to update Win says I have the latest driver. I am stuck as NanoVNA saver used to work, any ideas how to remove yellow triangle from Com Port 5 I think that's my issue or I am missing something else.
