PC crash during boss phase

I've replicated this multiple times: When fighting the Act 2 boss "Balbala, the Traitor", when she enters her poison cloud phase, my PC just immediately powers down. No freeze, no BSOD, no "shutting down" just power off.

Update: After further testing, I've found that the crash occurs when the poison cloud reaches the edge walls of the arena.

EDIT: I checked the log file and the logs do not show anything. Last minute of logs before crash just show local and global chat.

checked logs for info

Are you still facing this issue? I didn't find a fix for it, still happens from time to time with my game in some occasions.

I have the same GPU as you: AMD Radeon RX 7600
