I am using an HP Stream (64 bit) and running Arduino IDE 1.8.9 (Windows Store 184.108.40.206). I can upload and alter code without problems; however, when I click to open the Serial Monitor, the entire application crashes. I can reopen the application without trouble and keep programming and uploading to my Arduino/Genuino UNO.
The same problem occurred when using a basic ASUS laptop.
I have been unsuccessful reading others' posts for solving my crashing problem.
Thank you for any help you can suggest.
