Arduino IDE (Win10) crashes when I launch the program
I've got the same issue - the nightly build seems to work

I'm on Windows 10 having exactly this issue (same arduino_debug log).I tried uninstalling Arduino IDE and then reinstalling it from executable installer; it worked fine until I opened the Board manager: the problem recurs.
After installing the beta version (arduino beta1.9-BUILD-119), I'm not having any problem.
Just use the latest Arduino IDE Beta Version. It is working now, ignoring that issue. I'm using the ESP8266 board and it's running okay.
