Opening serial monitor causes visual studio to hang

Since some time in most cases this happened almost permanently.
No matter Visual Studio 2017/2019 or Microchip Studio.
It happens immediately or after some time.
Only kill task helps.

Other monitors (Arduino IDE, Putty, Teraterm, etc.) work with no problems.

Hi,

We dont have other reports of this therefore it would be useful to see your settings. We do have some extra features such as auto detect board/port, auto reconnect etc. that are different to the other terminals you mention. I think initially they should be switched off so that we can isolate the problem.

Can you please give the output requested in the yellow box above so that we can see which usb device(s) you are using. Also to give info of when this happens? When first connect or after some time? Huge stream of data or not? etc.

Thanks

Well, as it no concern with compilation, here is the of the Microdebug output prior to successive serial connection. To my surprise this particular connection works already several hours with no trouble and even was restored after hibernation.
Code
Select All
Launching Debugger...
   - Serial debug will start immediately. WiFi (or gdb) debug will start a few seconds or a short time after the remote device connects to the network.
   - Switch on 'vmicro>debugger>full speed' to prevent debugger message throttling. (read the docs)
   - If 'in-break live watch' is disabled, continue an existing paused debug session by sending the character 'c' to the board using the Serial window.
   - If uploading on WiFi but debug is on Serial then it is possible the cpu will be in debug break when OTA upload is attempting connect. If this is the case then sending char 'c' using the serial/debug terminal will force the mcu to continue (like F5).
   - WiFi debug? Wifi debug is not fully supported yet. Use the vMicro>Debugger menu to set an alternative debug port such as Serial (default speed is 115k)
   - To view debug messages without trace messages use the 'message windows' option on the monitor window.
   - Switch off this message and other Tutorial messages using the 'vMicro>General' menu

Thanks for the update.

If you could attach the build log with the settings shown at the top, it will help us understand all settings in and connected to Visual Micro which could affect this.
