NSTask launch crash due to EXC_GUARD

In my macOS app I launch the ffmpeg task in order to retrieve the media file information.

And I receive many crashes due to EXC_GUARD:

Exception Type:        EXC_GUARD
Exception Codes:       0x4000000200000001, 0xd71a2ae8e8dab339
Exception Subtype:     GUARD_TYPE_FD, id=0xd71a2ae8e8dab339, fd=1, flavor=0x00000002 (DUP)

Here is the code I use:

    NSArray *ffmpegArgs = [NSArray arrayWithObjects:@"-hide_banner", @"-nostdin", @"-nostats",
                           @"-i", self.media.path,
                           nil];
    self.task = [[NSTask alloc] init];
    [self.task setLaunchPath:[[NSBundle mainBundle] pathForResource:@"ffmpeg" ofType:nil]];
    [self.task setArguments:ffmpegArgs];
    NSPipe *errorPipe = [NSPipe pipe];
    self.task.standardError = errorPipe;
    NSFileHandle *errorHandle = [errorPipe fileHandleForReading];
    @try {
        [self.task launch];
    } @catch (NSException *exception) {
        NSLog(@"An exception %@ was thrown while attempting to launch the ffmpeg task with arguments: %@.", exception.description, [ffmpegArgs componentsJoinedByString:@" "]);
        [errorHandle closeFile];
        return;
    }
    [self.task waitUntilExit];
    NSData *outputData = [errorHandle readDataToEndOfFile];
    [errorHandle closeFile];

I can't reproduce this crash on my device.

Can anyone help me?
