Shadow of the Colossus [NPEA00280]

Hello, with the latest RPCS3 version, and using OpenGL, I could (almost) beat the game, with a low framerate (~15 f/s on an i7 6th gen with 32 GB DDR4 RAM and a Geforce GTX 770 2 GB VRAM). With Vulkan, the game seems very unstable (crashes after [30-300] seconds after booting).

But during the ending credits sequence, there is a fatal game freeze (when the "Character designer" section appears, that's about 30 seconds after the Credits Roll starts). It prevents the final game save to occur, and the further NG+ features (fighting bosses directly, collecting explosive arrow and so on). I tried 3 times, got the exact same error 3 times, at the same instant.

My machine is not overclocked, running at default/standard clocks.

The game is unaltered: this is a Playstation Network game (I read that the same issue was suspected to be caused by modified game files on some other games threads, but I modified none, nor did I get a shady altered copy of the game).

I play in windowed mode, maximized on a 1920*1080 desktop.

Here is the RPCS3 error log :
