Since patch 6.4, I have had issues where the game client sometimes locks up on startup i.e. before the SE logo pops up. Today it consistently would hang, so I reinstalled the game and reset system settings. I can now get into the game, however when I click on system settings in the game, the game once again completely freezes until I exit.

This does not happen if I access character configuration, or any other setting menu that I've thought to try.

Is there a file somewhere on disk that contains this that I can delete, or check the permissions on etc? Not sure what to try from here.
