I get an error called COM port is closed

[SteezyKane1]

Here is the error code I get from J Runner

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

** JIT Debugging ** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

I’m having the same problem I’ve got the latest update for j runner and pico uf2 v3.0

I had the same issue. J-Runner with Extras ver 3.2.2 PicoFlasher 3.0

After closing "NZXT CAM.exe", the PC was able to access the COM port with no issues.
