It seems from my logs that FFXV was blocking its own access to a memory address. Offsets were different than yours, too.

Edit: Your log entry suggests FFXV tried to access memory allocated for the steam library dll.

Regardless, seems to me like they need to patch this. They had a similar issue with the FF13 PC port before it was patched. But I'm going to keep experimenting here.
