My friend, who uses most of the same mods within the installer as me has had no crashing. I have had loads of locking up when exiting games, that go to the end. He does not have XVM services activated on the modxvm.com website, he has let the 14 day time lapse. I have been onto the site and reset mine so that it is not active and now I do not have any crashing. I also use the promod zoom out, but not the armour thickness mod.
So it might be worthwhile seeing if it is only affecting those with XVM stats activated?
I have only created an account today to post this to try help you troubleshoot.
