Arduino IDE crash when I connect Blend Micro
you should try to run the arduino from the consolle, on windows digit cmd on the search bar and the command promp program should appear.

Well, then you should navigate in out arudiono folder: digit cd "XXX" where XXX is the arduino executable location (something like c:/program files/blabla), you can copy paste it from the folder explorer.

then write arduino_debug.exe and you should see on the terminal the error appear; with that we may find the issue.
