UNO JAVA SE Binary Error

101 Rookie here, just bought the UNO and was running through the tutorials yesterday, all working fine, having a blast. I come back today and i'm following another guide to turn on pin 13.

So in void setup i type

pinMode(13,OU-----Dead

Java(TM) Platform SE binary has stopped working.

I've had a look around online, tried some things. Changing com ports, running as admin, trying an older version, uploading a blank and hitting the rest button. But it always crashes there, ive tried a few other combos, it seems whenever i go to type or change text that is blue i get this crash.

Running on windows 10-64.

Just very odd that it was working fine and now it isn't any help would be much appreciated.

Thankyou

You could try running the arduino_debug.exe file that's included in the Arduino IDE installation folder from the command line to see if there will be more information about the problem displayed in the command line window after it happens.

It would be best to find the solution but a workaround is to use the Arduino Web Editor:
