Well, the weirdest thing just happened.
I tried to recreate the situation to get a "crash dump" I could provide you.
Since the crash happened in both quality setting 6 and quality setting 4, I decided to play it again in the higher setting (6).
After a while, I decided to lower the setting (to 5) as the game was a little "laggy" and, wouldn't you know it, it did not crash during the credits!
Could quality setting 5 be the key?
