This appears to be a problem with the drivers. Communication is affected by software (drivers) installation. I recommend checking if the drivers are properly installed. Go to Start > Run > devmgmt.msc and check if there are any devices with a yellow sign. If there is, then most likely that is the cause to communication issues. Reinstall the application and the drivers for your device, then recheck that section again. Additionally, switch the port in the application to something else. Most of the applications nowadays feature automatic port detection, but if that doesn't occur, access the settings and manually choose the COM/USB ports.
