I encountered this problem when the form was closed!
After reading a lot of information, it was not resolved.
Form creation is like this
frm: = TFrmReport.Create (nil);
  frm.ShowModal;
  frm.Free;
No problem closing this form
Error when closing the main form! runtime error 216
The same code is beautiful in other programs!
Do not know what's going on!
It's urgent now, every time I close the main form, I will be prompted that the memory cannot be read, and then there is a runtime error 216
Sudden death!
Exactly the same code!
No problem in another project!
