Server 'localhost' existed with exit code -1073741819

Hello,

one of my students gets the following error

Server ‘localhost’ existed with exit code -1073741819.

on her laptop running Windows 10 (system locale: Korean) when controlling sound on the Window created by the following code:

~buffer = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01-44_1.aiff") 

(
// Assignment 3: Develop the code below using MouseX.kr, MoueY.kr and SinOsc.kr to control ```~speed```, ```~amp``` and ```~position```.
~controlWin = Window.new("Control", Rect(0, 0, Window.screenBounds.width, Window.screenBounds.height)).front;

~controlWin.onClose_{ x.free };

x = {
	~trig	= MouseButton.kr(0, 1, 1e-3);
	~fadeTime	= MouseButton.kr(0, 1, 0.2);
	~bufNum		= ~buffer.bufnum; 
	~speed		= 1;
	~position	= 0;
	~amp		= 0.1;
	~source		= PlayBuf.ar( ~buffer.numChannels, ~bufNum, ~speed * BufRateScale.kr(~bufNum), ~trig) * ~fadeTime;
	~sig		= Pan2.ar( ~source, ~position, ~amp );
	~out		= Out.ar(0, ~sig)
}.play
)

How could I resolve the problem? The SuperCollider version is 3.12.2.

The problem was resolved by reinstalling SuperCollider after erasing all files in Platform.userAppSupportDir and its subfolders.
