Crashed after level up

#1

Hello, so every time my hero level up by defeat another enemy hero, choose Exp when picking up treasure box, or interact with glowing experience tomb, the game sometimes crashed after that. I did load save and try to do the same thing before the crash, but it doesn’t work either. Does anyone have an experience like this and what could be the possible problem? Sorry if my English is kinda broken, thanks.

Oh right, now I’m allowed to attach files, so here’s the logs.
