//END OF LOGS

The game hanged between 13:06:25 to 13:07:14, when I selected the "Close the program" option in the not responding pane.
Windows quit the game on 13:07:17, just a second after this error message was displayed:
[13:07:16 ERROR]: Game ended with bad state (exit code -805306369)

This is not a memory problem. I think that Windows was deallocating memory from the unresponsive game, which caused this error to be shown.
