QReadWriterLock deadlock on stress test

[Lays147]

Hi!
I'm trying to lock and unlock thread for read and write functions on my arduino. Its seams look right, but when i make a stress test, the app freeze on a deadlock(i think) and my program stops.
This is my code, i'm doing something wrong?

void BrPrint3D::on_bt_table_clicked(bool checked)
{   this->mutexIno.lockForWrite();
    //QWriteLocker locker(&mutexIno);
    //if(this->mutexIno.tryLock(200))
    //{
    //QMutexLocker locker(&mutexIno);
    qDebug()<<"Lock Done - Mesa";
    if(checked==true)
    {
        ui->bt_table->setStyleSheet("background-color:red;");
        this->printer_object->setBedTemp(ui->tbMC_TableTemperature->text().toFloat()) ==true? qDebug()<<"Ok": qDebug()<<"~Ok";
        //qDebug()<<"Ok";
    }
    else
    {   this->printer_object->setBedTemp(0);
        ui->bt_table->setStyleSheet("");
    }

    /*else
        qDebug()<<"Timeout";*/
    this->mutexIno.unlock();
    qDebug() <<"Unlock done - Mesa";
}
