It took me quite a long time to find out the cause of the fall. Using the clipping method, I got to this plugin.
if you disable it specifically, the game is no longer crash. I also thought that maybe it was some kind of incompatibility, I was still ready to part with most of the other plugins, but not with this one. And I decided to disable all plugins, leaving only this plugin. the game dropped anyway... So I decided to write here.
How the fall occurs.
it's enough just to leave the game with the character editor in the background for a while and after a couple of minutes the game will crash.
Although sometimes it takes a little longer...
