      @lnyhcma Apparently you have a QVector that you try to access outside it's actual size, you should fix that.

      PS:
      Posting screenshots of error messages or code is bad, posting a photo of a monitor that displays the error message is even worse!

      Q: What's that?
      A: It's blue light.
      Q: What does it do?
      A: It turns blue.

            @J-Hilk l cannot fix that ...The size of all mine QVector arrays has not been defined, and when l try to access them,l use like
            for (int i=0; i<QVec.size(); i++) .

              @lnyhcma I suggest attaching a debugger and letting it crash and inspect the stack trace, should be possible, since the error message clearly states its a debug build.

              Should make identifying the issue easy enough
