Access violation reading location when chaning title of a menu.

[RedstoneMedia]

So i tryed to change the Title of the Menu but i get this error and i cannot fix it :( .
"Exception thrown at 0x00007FF629C35CD7 in annything-realy.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF"

It has to do something with the getWindow() function and m_pWindow but i dont know much more.

and i did not change StackMenu.cpp or StackMenu.h
