I'm playing the game in Honour Mode for the first time. I reached the battle in the Red Prince's dream. The game automatically overwrote the save when one of the party members died. On the next turn, Alexander acts, performing exactly four actions, and on the fourth action, the game completely crashes without any error—just the window closes.

When I reload the game, Alexander performs the same four actions, and the game crashes again.

What should I do? How can I fix this?
