[Spoilers] Gamebreaking Bug? Unable to progress?

After getting killing the Lothric brothers, I go back to Firelink Shrine and put the cinder back on the throne. I go talk to the Firekeeper and kneel before the bonfire. A cutscene plays.

However, my game crashes during the cutscene.

When I get back into the game, Ludleth is gone, and the Firekeeper gives me the dialogue to kneel before the fire. BUT I don't have the option of kneeling; I can only rest at the bonfire.

I have absolutely no idea what to do at this point.

Can any who has gotten this far can tell me if there is a way around this? Is this actually a bug preventing me from finishing the game?
