Delphi Firemonkey mobile app will crash when using Teechart

Question

I am developing an application, I have a main form and a button, when I click on a button I show another form that there is a TeeChart on it, when I close the second form and return to the Main Form the will crash (both ios Device and Simulator) and in log console on mac there is a "Exit with code:1" log. I test it on an Android device but it works fine. Any idea?

I found the problem, when you remove the graph form "Auto create forms" (in project options) and new the graph form in code and then close and free the graph form, the problem will happen, Instead let it be in "auto create forms" and when you want to show the graph use

frmgraph.show();
frmgraph.BringToFront();

and instead of closing the form use

Hide();
