Its seems like when the boss use her skill (shield?I am not sure), the game crash. It makes me can not finish the chapter.
I have try many times even restart the PC, it's didn't work.

I don't know if these info help:
I brought Cruel Keturah
I was using Chinese Language and running in a windowed mode at first, and after it crashed I changed to English and full screen but it didn't work.

if anyone knows how to fix it plz tell me, I will be appreciate.
Later, I will send the carsh files to support@defiantdev.com , hope they can find out.

然后我用中文复述一遍，如果有华语老哥知道的话希望能告诉一下怎么解决，不知道的话就当帮大家避雷了：
窗口模式，中文，打节制，boss战，boss一用技能就闪退，随从带的dlc的双枪老太太，其余的信息应该没什么用，就这些了
